active / passive setup(connected switch/router arp cache timeout)

L1 Bithead

I was starting to setup an active/passive system and once the HA was enabled, I lost connection to and from the internet.  I found it was an ARP cache on my router.  Now if my PA's failover the outside IP will startup and issue a new MAC for that IP and re-arp on router?  I was looking at my arp cache timeouts, I though I might have to tweek this?

anyone have any thoughts on this?

Thanks

When you enabled HA the MAC of the PANW changed to a virtual address. When a A/P cluster fails over the MAC doesn't change but will send a gratuitous arp and your switch/router *should* pick that up.
