I'm restarting a post, because I think my questions are more basic than the one I actually posed.
Let's say my Firewall is behind a router, the router configured as
192.168.1.0, 255.255.255.0 and I want to assign a block of IPs to my 506e firewall.
What do I set the outside IP address, SNMask of the firewall?
I recently tried 192.168.0.241, 255.255.255.0 and it fixed up most of the problems I was having, but now users behind the firewall couldn't get out, and some, but not all, users in the 192.168.0.1 subnet lost access to the internet.
I tried configuring the firewall to
184.108.40.206, 255.255.255.240, and couldn't get access to servers behind the firewall. When I changed the 255.255.255.240 to 255.255.255.0, I could get access to the 'protected' servers, but with the problems listed above.
