James, I think it would help if you thought of the Two PIX 535's Primary and failover as one firewall not two. Let me explain. A Primary and failover unit do not function as independent units. They act as one. The scenario you out line in your messages would require that you purchase a second primary or upgrade your failover license to a primary for the new site. Bill Tedeski ACS Inc.

I'm working at a university, that currently only has a single gig feed to the outside world. In the interests of resilience, we're soon to be getting a second feed in, and I was hoping that someone might be able to offer some advice on the best way of going about it. We've currently got two Pix 535's as a failover set, one with an unrestricted (UR) license, the other with a failover (FO) only. As the new feed is coming into a different site, the failover Pix will be moved, and we'll do LAN based failover rather than using a failover cable. *However*, the educational body supplying the new feed has seen fit to provide the second feed in as a separate OSPF instance to the original feed. Therefore, each of the two feeds out will have different OSPF instances, and different IP addresses. For the sake of arguement (which will likely as not prove to be fact anyway), assume that this is set in stone, and nothing's going to change it. So, what I want to know is your thoughts on how best to go about this... Is it possible to have to firewalls in a failover set failover as normal, but have the failover Pix have a different outside IP address? I didn't think that this would be possible, if at all, but especially on a box with an FO licence? What about upgrading the licence from FO to UR - would that allow it? The best possible solution I've managed to come up with so far, is to have two routers (or L3 switches) - just outside each of the Pix's - configured for HSRP. If the main link goes down, what I would like to happen is for the other router to take over via HSRP, and for the firewall pair to failover to the backup. Does that sound feasible? I hope I'm making sense. Any help is appreciated. -- James Burns Network Advisor ? Student & Learning Support University of Sunderland
