I was going to setup my two ASA 5510's in an active/standby mode, but after reading I figured I'd look more into the setup of using a dual setup as follows. Firwall 1 just after the ISP router to filter traffic. Traffic is either denied or only granted access to the DMZ. Firewall 2 would then would filter traffic to the internal network. Only specific traffic from the DMZ would be allowed to the internal network or it would be dropped. No traffic from firewall 1 would be allowed direct access to the internal network.
Does anyone know of a guide to setup Cisco ASA 5510 firewalls in a front-end and back-end environment? I can't find a resource and think my terminology may be wrong.
