Forwarding vs Port forwarding

[guenhter]

Hi,

I'm new to gost and might not have understood all concepts already. The question I'm having is, what's the difference between

./gost -L=udp://:4501/:4511

and

./gost -L=udp://:4501 "-F=udp://127.0.0.1:4511"

---

I can clearly see a difference in my udp server which runs on 4511, but I don't understand the difference though.

What I want to achieve is, to forward my udp data to a remote server via an ssh tunnel. So on the client I need to receive the UDP data, send them through the tunnel and on the server side, receive the data and forward them again as UDP to the actual destination.
