Subject: Cisco VPN Client Behind Firewall
 
We recently rolled out a remote access tool that requires the Cisco VPN
Client.

It is working all over the world with no issues.....except for some
personnel we have on vendor/customer sites which are behind another
companies corporate firewall.

I have found that there are multi-ports required and all of them must
be source and destination matched, but does someone know of any
information available {web site etc} that would tell what changes are
required for specific brands of firewalls?

Such as:

CheckPoint requires XXXX changes.
Sidewinder requires XXX changes.
etc......

I would like to know if the information is available because then I can
point these other companies to the URL of the site and they can then
decide whether or not to make the changes to their systems.

Thoughts would be appreciated
