Core issue
The primary PIX Firewall shows the interfaces on the secondary PIX with an IP address of 127.0.0.1. The configuration does not have failover ip address commands.
Resolution
To resolve this issue, an IP address must be assigned to each interface on both the primary and secondary PIX Firewall.
To assign IP addresses to the interfaces of the secondary PIX Firewall, issue the failover ip address if_name ip_addr command.
Note: This command must be issued from the active PIX Firewall.
This is an example of this command:
failover ip address outside 192.168.1.2
failover ip address inside 10.10.10.2
failover ip address intf2 172.16.1.2
For more information on configuring failover, refer to Using PIX Firewall Failover.
