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

  1. General: In the Task field type in Install WYL. Uncheck the “Enabled” option. Select root User.
  2. Schedule: Select Run on the following date then select “Do not repeat“.
  3. Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that, click OK.
docker run -d --name=WatchYourLAN \
-e TZ=Europe/Bucharest \
-e GUIIP=192.168.1.18 \
-e GUIPORT=8840 \
-e IFACE=bond0 \
-e THEME=darkly \
-v /volume1/docker/wyl:/data \
--net=host \
--restart always \
aceberg/watchyourlan

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 GUIIP 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 IFACE 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
  • wg0
  • lo
