udp port forwarding in virtualbox

Open andry81 opened this issue 1 year ago • 2 comments

I've tried to tcp/udp port forward vpn connection from guest-with-vpn to guest-with-emule and have found that the udp port forwarding is not working in case of different ports:

>socat.exe TCP4-LISTEN:42586,fork TCP4:192.168.100.6:42586
>socat.exe UDP4-LISTEN:42586,fork,reuseaddr,bind=0.0.0.0 UDP4:192.168.100.6:42588

emule-tcp-udp-test-fail

If change udp port from 42588 to 42586, then test does pass completely.

I suspect there is some issue inside emule.
