Hello,
I I have Paloalto 1410, working fine but we use the arp entries too many on the interface.
I know it has max of 3000 arp entries, is there any way to maximize it or use external server as IP - MAC entries to depend on which may enable me to have more the 3000 records?
TIA

Hello @MRamadanAHafiez
thanks for posting!
As a first step could you check this KB: How to reduce the ARP table size. It is not possible to increase ARP table size. Personally, I would be looking into different design to reduce number of ARP entries in Firewall. For example considering implementing a L3 switch to maintain MAC / ARP entries and have Firewall connected by L3 routed port to avoid flooding Firewall interface with all ARP entries from clients.
Kind Regards
Pavel
