RUTX11 with firmware 2.06.1 and RUT240 with firmware 1.14.3.
In the Wireguard GUI, I've created a tunnel between the 2 routers. I then wanted to edit the RUTX11 and the RUT240 so that I could try an MTU of 1440, however the GUI throws an error, outlining the number with a red box, and indicating that the maximum value is 1420. As Im running an IPv4 network, I should be able to set it to 1440, and still keep the total size to 1500 even including the Wireguard headers. I havent tried setting it in CLI as an option, but wonder if this GUI behaviour is correct?
