SOCKS5 has still a TCP connection on the local side of the SOCKS proxy.
If your connection to the JEP-proxy is TCP and your application works
with that, I guess you should be able to transfer the entire protocol on

I don't say, that audio/video should be done over TCP ... no, I really
advise everyone to use UDP for that. But I guess a JEP-proxy supporting
UDP on the remote side and TCP on the local side won't help you in this
case either.

I guess it was on this list where it has been discussed how to pass NAT
with UDP packets.

(As UDP is connectionless, you won't get any benefit by using a proxy
that speaks UDP on both sides, you would just have the case where you
directly communicate with someone else using UDP.)

... yes ... NAT is horrible and only neccessary because there are far to
few IPv4 addresses. Why can't the internet just kick IPv4 and only use
protocols with at least 2^128 addresses (e.g. IPv6) ...

Tot kijk
