Is there any tool through whih i can route telnet to a specific port and IP from any other host. Like I have 3 systems system A is only allowing System B to telnet A on port 80, when B telnet to A on 80 it is successful but when C tries it fails. I want a tool on which we can specify the Source and Destination IP Love Gnome!

This doesn't sound like a routing issue. C going to A is most likely using port 23 whereas A is configured to receive on port 80. Also check your firewall settings on both to make sure c isn't blocking telnet and a allows c's access

I agree, you might misunderstand or are not asking correctly or we don't get it. HTTP is on port 80 normally. If you try to telnet to a HTTP server port 80 it will connect and serve pages if you know how. See pages on telnet port 80 for how-to's. Telnet to a port that a machine can listen to and reply on is the firewall issue also. RFC 854 May 1983 CONNECTION ESTABLISHMENT The TELNET TCP connection is established between the user's port U and the server's port L. The server listens on its well known port L for such connections. Since a TCP connection is full duplex and identified by the pair of ports, the server can engage in many simultaneous connections involving its port L and different user ports U. Port Assignment When used for remote user access to service hosts (i.e., remote terminal access) this protocol is assigned server port 23 (27 octal). That is L=23.
