I have a pair of 3.9 pf firewalls running CARP. I have two ethernet connections to my provider who is running Cisco HSRP. When they reload the active router or bounce the active interface, then the Ciscos can no longer see the CARP virtual interface until I cause a CARP failover by rebooting the active firewall or admining down the external interface on the active firewall.
Through all of this, I have outbound connectivity from the firewall since it is on the same subnet as the Ciscos. I am not sure if anyone else has experienced this, but I am sure Cisco won't fix it. Thanks in advance for your help. Scud
