Connection reset

[Olivier Nicole]

Hi,

I am trying to run NoCat (from the ports). One thing NoCat does is run
a TCP listener on port 5280.

When I try to connect to that port "by hand" (telnet xxx 5280)
everything goes fine.

When I try to connect via a redirection through the firewall, I got a
RST after the SYN, SYN/ACK, ACK.

What could be the reason that the connection is reset by the server at
that stage?

The server is build around Perl IO::Socket

Thanks,

Olivier
