Gratuitous / Proxy ARP in Failover

Hi,

I know that PA sends out an Gratuitous ARP in Failobver to inform the network partners that the active IF-IP has changed. But waht about the configured static NATs on the Public Network which redirects traffic to internal Servers (e.g. DMZ) ?

Are there also Gratuitous ARP send out for those "Proxy Arp" Adresses?

I ask this because at a customer site the Static IP Mapping will no longer work after an failover till the router in front will be flushed the arp cache?

Any answers welcom.

Stefan
