Hi there.

I have configured my CISCO ASA 5500 with 3 zones:

INSIDE: 192.168.1.x
DMZ: 192.168.2.X
OUTSIDE: 100.20.1.1

The PCs (Windows XP) connect to the inside interface have IP adress 192.168.1.x, mask 255.255.255.0 but:

Which should be default gateway? 192.168.1.1 or 100.20.1.1?

Thanks.

The default gateway for PCs on the LAN will be the IP address assigned to the inside interface on the ASA (presumably 192.168.1.1 in your example).

I always describe the Default Gateway to my customers as the door to the internet, or the exit in a theatre from the auditorium, which then leads you to the main entrance / exit.
In your case as willsorrell has advised, your Gateway is 192.168.1.1.
Hope the analogy helps!
