server setup question

[artworcs]

I was wondering how can i set up a gateway if the server connects to the internet through a socks5 proxy? I don't want the other machines to use a proxy, but to transparently forward all the data to the proxy server and back. I need this not only for http, but for telnet and other services to.

You could use a firewall with port forwarding, although it will probably be a P.I.T.A. to set up.

I really need this, so if you could specify how to do this, at least the theory, to know where to start.

applications should speak socks protocol (CONNECT, BIND, etc)
u can't have this transparently.

[artworcs]

I understand one can do transparent proxy with squid. But can one use this for other protocols as well, not just http? I'm thinking of ssh, telnet...

PS: the server can run any kind of proxy/tunnel, but CAN'T DO NAT!

[makoomba]

transparent proxying works with squid (http/ftp) because the application do not have to modify the way it connects to remote sites.
SOCKS requires clients to speak socks protocol, so they have be aware of the proxy.

[artworcs]

How does squid get the information to where to connect when using it transparently? Something in the http headers? w

[makoomba]

yes
