"Poxying UDP traffic unsing SOCKS 5"
I must admid that I have no Idea how thats works. Does the "end-user" have
to do any configuration on his gateway to acomplish this?
The problem is, I am sitting beyond a router which I do not administrate and
there is no way the administrator would forward a port to me.
After your answer, I am not sure, do I have to use TCP?
Thanks again
