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.
