Re: Reverse SSH tunelling

Raistlin ,

    I have another idea thats more simple than yours , you should contact
your firewall manager and ask him if there is a way to authenticate against
the firewall (i know that Nokia Firewall-1 and Cisco Pix allow that) , once
you authenticated with the firewall you have special rules to access
services that are running on your servers. This services would be only
reachable by an authenticated user.
