How to Install WatchYourLAN on Your Synology NAS

WatchYourLAN, or WYL for short, is a Lightweight network IP scanner with web GUI that can be personalized with different themes. WatchYourLAN looks like a good project with a lot of room to grow. In this step by step guide I will show you how to install WatchYourLAN on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest WatchYourLAN v2.0.4 release.

Once you click on User-defined script, a new window will open. Follow the instructions below:

docker run -d --name=WatchYourLAN \
-e TZ=Europe/Bucharest \
-e HOST=192.168.1.18 \
-e PORT=8840 \
-e IFACES=bond0 \
-e THEME=grass \
-e COLOR=dark \
-v /volume1/docker/wyl:/data/WatchYourLAN \
--net=host \
--restart always \
aceberg/watchyourlan:v2

Note: Before you paste the code above in the Run command area below, change the value for TZ. (Select your current Time Zone from this list.)
Note: Before you paste the code above in the Run command area below, change the value for HOST and add your own Synology NAS Local LAN IP. 192.168.1.18 is my NAS local LAN IP, you should use your own NAS local LAN IP.
Note: Before you paste the code above in the Run command area below, change the value for IFACES and add your own Network Interface that you previously get via email at STEP 7. bond0 is my own interface, you should use your own interface. If the first interface you found on email at STEP 7 is not working for you, try another one from the list you get via email. docker0 is not supported as a network interface. Make sure you have selected root as user (not the current NAS user) at STEP 7 point 1 before you run the script. The most common interfaces are:

  • bond0
  • eth0
  • ovs_bond0
  • enp1s0
  • enp2s0
