[GRLUG] CentOS IP Weirdness

[Dave Chiodo]

Ok, wait.. I'm  bit fuzzy on what the setup is.

You are trying to connect to the LOCAL end of a forwarded port? If so,
what it listens on will be controlled by the arguments you give ssh.

This might be simpler to sort out if you show the actual commands you
are using to setup this tunnel (redact specific IP's if desired)
