Hi all
Let's say we have two ISA in integrated mode configured in firewall
chaining. Let's call them low and high. The low is configured to chain to
the high one. They are not directly connected on the same LAN, there is
routers between them, with most ports closed.
What are the ports that need to be opened between them so that firewall
clients using the low one can access services like smtp or http, or other
ports?

Thanks in advance

Olivier
