Re: [FW-1] Nokia IPSO cluster - secondary answering arp requests

[Shawn Behrens <shawn.behrens@FW1-NOSPAMACTIVIS.COM>]

The proxy ARP on both firewalls should be set up with the VRRP MAC address,
not the interface MAC. That way, both might respond, but traffic goes to the
VRRP MAC, which is handled by the master.

Did you set your proxy ARPs up with VRRP MAC or the physical interface MAC?
