Re: Tunneling other protocols over TCP port 80

Then if you wanted better security (not in the clear telnet) then you can use ssh tunneling to port 80.

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,
