How do I make Telnet work through my firewall?
Telnet is generally supported either by using an application proxy such as the firewall toolkit's tn-gw, or by simply configuring a router to permit outgoing connections using something like the ``established'' screening rules. Application proxies could be in the form of a standalone proxy running on the bastion host, or in the form of a SOCKS server and a modified client.
