How to Remove Blocked IP Address From Synology NAS
If you are using Synology NAS, you may have seen that the device is blocking the local IP address of certain devices once too many failed login attempts happen. It won’t happen frequently, but in some cases, if any device connected to the Synology NAS failed to log in and tries reconnecting again, the Synology NAS might block the device’s IP address.
In this article, we are going to check, how we can remove blocked IP addresses from Synology NAS. By unblocking the IP address, you can continue using the Synology NAS, without any issues.
IP Address Blocked By Synology NAS
If you are using Synology NAS within your network and trying to use any of the Synology Services like Synology Photos, Synology videos, etc on your phone, tab, or PC, then you need to log in using the local Synology Account. In some cases, due to the system update or some other reasons, the login to the device might cause the issue.
If the device that is used to access the Synology service, whether it is a phone, tab, or anything failed to log in continuously multiple times, Synology will add the IP address of that device to the blocked list. So, you won’t be able to use the Synology service on that particular device, until you manually unblock the IP address.
How to Remove Blocked IP Address From Synology NAS
To remove the blocked IP address from the Synology NAS, follow the below steps.
Step 1: Log in to the Synology NAS using the admin username and password,d
Step 2: Got the desktop and click on the Control Panel option.
Step 3: From the control panel, Click on the Settings menu.
Step 4: From the setting section, Click on the Protection tab.
Step 5: Within the Protection setting, you will find a button Allow/Block List. Click on that.
Step 6: Now a popup window will appear showing all the Allowed and Blocked lists. Click on the Block List Tab item.
Step 7: You will see the blocked IP address within the list.
Step 8: Now click on the IP address that you wish to unblock. Then click on the Remove Button.
Step 9: Finally a confirmation window will appear asking for the confirmation. Click on the Delete button.
Done, the IP address is now removed from the block list and is now unblocked. You can now try login in again from the previously blocked device and will log in now without any issue.
In this way, you can unblock the blocked IP address from the Synology NAS easily.
Synology ip адрес заблокирован так как достигнуто максимальное
Знаете как обнаружить, что ваш Synology NAS пытаются взломать? Как защититься от подбора пароля? В этой статье я расскажу как это можно настроить.
Так уж завелось в интернете, что в этой глобальной сети обитают не только сервера, ПК и телефоны, но еще и огромная куча зловредных ботов. Задача этих ботов найти уязвимое место и бить туда пока не пробьют дыру в вашей защите. А мы все знаем, что Synology NAS покупают именно для того, что бы он был личным облаком доступным с любой точки мира, где есть интернет. И поэтому наш NAS становится лакомым кусочком, который хотят оттяпать.
Так было и с моем Synology NAS, когда я обнаружил многочисленные попытки подбора пароля. И тут я расскажу ответ как я это узнал. А все дело в том, что в DSM есть приложение “Центр Журналов”, в котором можно увидеть все логи, все попытки и все удачные и неудачные входы.
В этом центре журналов достаточно перейти на пункт “Журналы” затем выбрать “Подключение” как показано на скриншоте выше и отобразятся все попытки входа. В моем случаи попытки авторизации были неудачными и они продолжались бесконечно и постоянно с разных IP адресов.
Конечно можно зайти в брандмауэр и заблокировать все эти IP адреса. Но как часто вы будите это делать? И сколько времени будет уходить у вас на такую работу? А если не успеете и пароль подберут? В DSM можно автоматизировать этот процесс.
Для этого переходим в панель управления, безопасность и защита. Включаем автоматическую блокировку и выставляем более суровые значения, чем стоят по умолчанию:
Я выбрал для себя такие: если с одного IP адреса будет сделано 3 неудачных попытки входа в течении суток, то заблокировать этот IP адрес на 30 дней. Это сугубо мое решения, возможно такие значения для вас будут неприемлемыми. Обычно я всем рекомендую ставить 4 неудачные попытки входа в течении часа и блокировать на сутки. Но как видите в моем случаи пришлось делать по другому.
В результате за ночь получил кучу уведомлений о блокировке:
Список заблокированных начал заполняться нежелательными IP адресами:
Этим адресам можно сделать экспорт, а затем импорт и в результате заблокировать их навсегда.
Так же нужно подстраховаться. Внутри вашей локальной сети вы должны быть уверены, что зловредов нет. Соответственно не блокировать IP адреса из вашей локальной сети настроив список разрешенных сетей, которые никогда не будут заблокированы:
Вот такими не хитрыми настройками можно автоматизировать процесс блокировки ботов, которые пытаются подобрать пароль к вашему Synology NAS.
Дополнительно нужно настроить брендмауэр. Как это сделать я уже рассказывал.
Защита от подбора паролей очень важна, но еще важно периодически обновляться. Так как в обновления закрывают уязвимости, через которые можно проникнуть на ваш NAS даже не зная логина и пароля.
Что бы получать такие обновления автоматически, переходим в панель управления, обновление и восстановление, нажимаем настройки обновления и устанавливаем автоматически устанавливать важные обновления, как это и рекомендует Synology.
Еще рекомендую зайти в панель управления, пользователи и группы, на вкладке дополнительно включить галочки как показано ниже и установить минимальную длину пароля от 8. Это повысит защищенность вашего Synology NAS.
Все действия в статье не хитрые, но сделать их нужно, так как в интернете с каждым годом становиться все опаснее и опаснее. Берегите себя и ваши данные.

This ip address has been blocked synology
Why does Synology say this IP address has been blocked?
This IP address has been blocked because it has reached the maximum number of failed login attempts allowed within a specific time period. You can still sign in to your DSM account from a device with a different IP address.
How do I block an IP address on Synology Diskstation?
Go to Network Center > Security > Auto Block. Click Allow/Block List. On the Block List tab, select either of the following from the Create drop-down menu: Add IP address: Enter an IP address and expiration time.
How do I reset my Synology IP address?
Press and hold down the RESET button for about 4 seconds until you hear a beep. Release the button immediately. Within 10 seconds, press and hold down the RESET button again for 4 seconds until you hear 3 more beeps. Wait for about 2 minutes until the STATUS light on your Synology NAS blinks orange or green.
What causes an IP to be blocked?
IP addresses are blocked for multiple reasons, including to enforce standards for online behavior (e.g., a school restricting its students from accessing certain websites), protect networks against attacks, and censor access to information. All devices connected to the Internet have unique IP addresses.
What does it mean when IP address is blocked?
IP Address blocking is a security measure that prevents a connection between a specific or group of IP addresses and a mail, web or Internet server. This is usually done to ban or block any undesirable sites and hosts from entering the server or node and causing harm to the network or individual computers.
What happens when IP address is blocked?
IP address blocking or IP banning is a configuration of a network service that blocks requests from hosts with certain IP addresses. IP address blocking is commonly used to protect against brute force attacks and to prevent access by a disruptive address.
Is it legal to block an IP address?
IS IP BLOCKING LEGAL? No, it is not legal to block IP addresses. In 2013, U.S District Judge Charles Breyer in the Northern District of California had ruled that blocking an IP address from connecting to a website is a breach of the Computer Fraud and Abuse Act (CFAA).
Can you block an IP address?
By discovering the IP address of a device or website that is causing trouble to an internet user, that user can block the address using a rather straightforward process. The process of blocking an IP address may change depending on the operating system that is used by the internet connected device.
What causes an IP to be blocked?
IP addresses are blocked for multiple reasons, including to enforce standards for online behavior (e.g., a school restricting its students from accessing certain websites), protect networks against attacks, and censor access to information. All devices connected to the Internet have unique IP addresses.
Can you remove IP ban?
It depends on the type of ban. If it’s a simple IP ban, connect to a VPN server to change your IP address, and you’ll be good to go. If it’s an account ban you need to both register a new account and connect via a VPN to get back in the game. CyberGhost VPN works great for Fortnite gamers.
Why is IP restricted?
Usually, the IP block occurred because of one of the following reasons: You logged in from a public network like the ones in a bar, a train or an airport. Other people used this public IP address for suspicious activities, causing it to be blocked.
Why can’t I connect to my Synology Diskstation?
Make sure that the LED indicators of the connected LAN ports on your Synology NAS are flashing properly. Make sure that the LED indicators of your switch or router are flashing properly. Run a PING command to check the connectivity between Synology NAS and your computer. Refer to this article for more details.

Synology NAS Says ‘This Site Can’t Be Reached’: How To Fix This
Synology’s NASes are usually fairly reliable. You plug them into your home network, and then you can easily access them via file explorer or a web browser. However, sometimes things… go awry.
When you try to access your NAS over a web browser (either to transfer files, or simply to manage it via the DSM admin panel), you get an annoying “This Site Can’t Be Reached” error. Unfortunately there can be quite a few reasons why you see this error, so let’s drill into why this error might appear – starting with a brief recap of how a NAS connects.
Contents hide
Overview: How Synology Connects
A Synology NAS is usually connected to your home network via an ethernet cable: by plugging one end of the cable into your NAS, and the other into your router (or a network switch). This then allows your NAS to be accessed anywhere in your home, hopefully allowing super-fast file transfers.
You can also access your files (and the admin panel) through your web browser by navigating to http://synologynas:5000 – or if you know your NAS’ IP address, by going to http://ipaddress:5000 . This is known as local LAN access, and it usually starts with “192”.
If you are away from your home, you can access your NAS by launching your web browser and going to http://quickconnect.to/username (assuming you have enabled QuickConnect, of course). This is known as external/internet access.
Key Point: It is important to know whether the URL you are using is a local or external address, because no-one will be able to use a local address (starting with http://synologynas. or http://192. ) outside of your own home network. I will discuss this point in more detail later.
However whether you connect locally or externally, you might sometimes get an error in your browser like “This site can’t be reached: (site) took too long to respond” or “This site can’t be reached. The connection was reset”. While this is a frustrating error, there are often some simple fixes for it.
Fixing The “This Site Can’t Be Reached” Error
This error is particularly annoying because it’s just so vague! It would be better if it said “Your Synology NAS has a port forwarding issue” or “You are trying to access your NAS using the wrong URL”! However your web browser simply doesn’t know exactly why your Synology NAS is acting up (or that you are trying to access a Synology device), so it is forced to give the vague error instead.
Let’s dive into why you might get this error, and how you can resolve it. There are a range of possible causes, but I will start with the most likely ones.
Double Check That Your NAS Is Actually On!
This might seem obvious, but it’s worth double checking. If your NAS is off, you can’t access it. Who knew? But (half) joking aside, if you can’t directly see your NAS, you might assume that it is working fine – when it is actually having issues (or turned off).
This will naturally lead to you getting the “This site can’t be reached” error because the web browser quite literally can’t access your Synology NAS.
You should double check your NAS, ensuring that it is turned ON (shown by a blue light around the power switch) and the disk and LAN lights are flashing green (showing they are working well):
Pay particular attention to the ‘status’ or ‘alert’ LED, too, because an orange LED could be a sign of an internal issue with your NAS. If you do see an orange LED, check out Synology’s specific help page for orange LEDs.
At Home? Confirm You Have The Right URL
It’s really useful that you can go to “ http://synologynas:5000 ” and your NAS admin panel loads up, but this shortcut URL doesn’t always work reliably. The “ synologynas ” hostname works well for me on a Windows computer, but it never works when I’m on my Chromebook.
So if you are at home and trying to connect locally to your NAS, you might want to try connecting to the IP address instead. To do this, launch http://find.synology.com/ and it will scan for your Synology NAS on your home network. If it finds it, it will give you the IP address ( 192.168.4.240 in my case):
You can then go to “ http://192.168.4.240:5000 ” in your browser (changing the IP address as appropriate), and this should hopefully load. It will definitely be more reliable than relying on the “ synologynas ” shortcut, if you use non-Windows operating systems.
Away From Home (Or Sharing Photos)? Use The External Address
If you are out of your home, or you are trying to share NAS access (or Synology Photos) with friends, you will need to ensure that you use the external address to connect to it. After all, a URL like http://192.168.4.240:5000 (or http://synologynas:5000 ) will not work outside of your home network.
This is because a local URL can only ever resolve to your NAS from within your home network. The moment your device connects to another Wi-Fi network (or LTE network, if you’re on a phone), you will not be able to connect to your Synology NAS using local access.
You will instead need to use external access, i.e. by enabling QuickConnect and then navigating to http://QuickConnect.to/username in your web browser. This is also the URL that you would need to share with friends or colleagues, whether you’re trying to show them photos from Synology Photo Station or you want to grant them access to your NAS’s files.
Check That QuickConnect Is Enabled
Naturally though, the QuickConnect.to service will only work if you have enabled QuickConnect within your NAS. It might also be possible that it was enabled in the past, but you briefly disabled it ‘as a test’ – then forgot this. Either way, you will need to enable it again for proper external access.
You will need to be at home to enable QuickConnect, because you will firstly need to go into the DSM admin panel, and then go to Control Panel and “Quick Connect”. From here, tick the “Enable QuickConnect” option:
If you don’t currently have a Synology account, you will need to register one because QuickConnect requires this. One you are signed up (or logged in) to Synology, you will see a QuickConnect URL that starts with “ http://QuickConnect.to/ “. It is this URL that you will need to use (or give to friends) whenever you’re away from your home network.
Are Your Port Forwarding Rules Set-up In Your Router?
While QuickConnect can sometimes work ‘out of the box’, you might also need to set up port forwarding rules to improve external access speeds and reliability. Port forwarding is a way of telling your internet router that “all traffic to the following ‘point’ should be routed straight to my Synology NAS box”.
While Synology can sometimes create these port forwarding rules automatically (within your router), you might also need to manually create them. The first step though is to go to the Synology admin panel, click “External Access” then “Router Configuration”:
Assuming you don’t have anything set up here already, click on Create and following the steps shown in the wizard. Hopefully Synology will be able to automatically configure things at your router. But if it can’t, it will tell you what port forwarding rules to create.
You will then need to load up your router’s admin console or app, and find the port forwarding page. Then input the relevant details. While this might seem confusing and overly technical, you are essentially saying that “traffic to the following ports should go straight to my NAS”.
In the case below, I have created a rule that ‘reserves’ an IP address (and port forwarding point) for my Synology NAS with local IP 192.168.4.240 :
I then specify exactly what external traffic should be automatically routed (port forwarded) to my local Synology NAS:
Rule Out IP Address Conflicts
If you have used Windows for many years, you may have randomly seen an error appear that says: “Windows has detected an IP address conflict”. This weird-sounding error means that more than once device in your home has tried to ‘reserve’ the same IP address within your router.
However IP addresses should be like house addresses: there should only be one per device (or per house). So if more than one device is trying to reserve the same IP address, it will be impossible to access one or both of those devices (from other devices in the network).
The same is true for your NAS: if your Synology device is trying to reserve the same IP address as another device on your network, you probably won’t be able to access your NAS.
Unfortunately fixing this specific issue can be difficult, and even Synology’s help guide for an IP address clash is quite vague. I personally just restart every relevant device, and this fixes the problem 90% of the time. So if your NAS is plugged into a network switch, and this network switch connects to your router, reset all these devices:
- Reset your Synology NAS.
- Restart your network switch.
- Restart the router too.
- Also restart any device that you suspect might be having the IP address conflict (such as a Windows PC that complains about “IP address conflict” detected.
Tip: You might also want to reserve your NAS’ IP address within your router’s admin panel (or smartphone app), as I shown in the port forwarding section above. This will help to ensure that other devices can’t accidentally ‘steal’ your NAS’ IP address in the future.
The following YouTube video explores the reasons for this issue (and how to fix it) in a bit more detail – and while it is Windows-centric, the same concepts apply for investigating this issue with your NAS:
