I have an existing PIX 515 failover pair. I am installing a second circuit (more bandwidth needed) and will be using a second PIX 515 failover pair. Both outside interface IPs will be in different networks eventually. Both inside interfaces will be in same net work (x.x.x.16 255.255.255.240). I need to keep the inside firewalls on same network if possible, but testing did not allow traffic to pass on PIX-2. (testing was done with outside networks in same network on 1 ISP link. This worked through small linksys router, but not on PIX) Any advice would be appreciated. I am assuming there is a conflict on PIX due to them both advertising or being in the same networks (x.x.x.16 /27 inside and x.x.x.0 /27 outdside) and connected to them.
Thanks in advance!
