ProxyARP default setting

[RamBalaji]

Hi Team,

               Is ProxyARP is enabled by default. Can we disable or enable this feature in PA??

with regards,

hi @RamBalaji

ProxyARP is enabled by default and cannot be disabled, but it will only work for addresses you set in NAT rules

so if there are no NAT rules, or NAT is only applied to IP addresses already assigned to physical interfaces, there will not be any Proxy ARP

Thanks, can you give any document which says its a default function or cannot not be disabled?? customer may ask it.

with regards,

Ram

Hi Ram

the admin guide : https://www.paloaltonetworks.com/documentation/80/pan-os/pan-os/networking/nat/nat-policy-rules/prox...

it's a function of NAT (so you basically 'enable' it by configuring NAT rules)
