@Vexari So I haven’t tested udp-proxy-2020 with that router. A quick google search says it runs a flavor of Linux. I release binaries for various flavors of ARM on Linux so it should work if you copy the appropriate binary (you’ll probably have to test a few to see which works) and figure out how to get it to auto-run at boot as a service.
That said, you will probably need to ask for help from a forum that knows more about that router and it’s OS than I do about that last part.
