Bad security policies aside.... :)

You could always run the telnet server on port 80. Or run netcat (aka nc) on the box on port 80 redirecting to port 23.


He could, if he wanted to really violate the policies in place and tunnel traffic in the clear. he's actually asking about something that would be deemed a tad more seucre/private in nature, though still likely a violation os the security policies currently in place and thus subjecting himself to likely termination once the tunnel was discovered, let alone potential prosecution.

Hi guys,

I need to create a VPN to my linux server from a remote workstation(windows) inside a private network of another company. The LAN where the workstation is located is protected by a firewall. This firewall only lets pass through outgoing traffic to port 80(http).

I need this workstation to telnet a telnet server inside my private network. Is it possible to set up a tunnel over port 80 to create a VPN between the workstation and my gateway, so that the workstation can telnet my internal server?

The network administrator where this workstation is located is inaccessible, so I have to create this workaround.

Thank you,
