[aklug] Re: Proble with CGI connection, getting nowhere with tech support

Port 23 eh. Map it to 2222 -> 23 on the linksys with help from the network admins. Not saying this
is the problem, however I would avoid using telnet ports. They make dynamic firewall and packet
inspectors crazy.

If your office IP is, for lack of the correct term, banned every so often for a short period of time
that you haven't quite guessed yet then active network intrusion countermeasures may be in place.
Thats right.. countermeasures - You guys saw Sneakers and The Net right? They always say
countermeasures.
