proxy_arp_pvlan feature request

Dear Palo Alto support team

As I have post my question in the community, I come to conclusion that the Palo Alto firewall does not support the feature explained in the post--https://live.paloaltonetworks.com/t5/General-Topics/proxy-arp-pvlan/m-p/302528#M78834.

The design case is used the the private vlan scenario where the upstream router/firewall with promiscuous port should reply to the isolated vlan clients in order to inspect the traffic between the isolated VLANs.

In the Linux kernel, this feature is called the proxy_arp_pvlan which is disabled by default. The path to enable this feature is under the /proc/sys/net/ipv4/conf/all/proxy_arp_pvlan

In other vendor terms, it is supported with the following name:

Cisco == ARP alias
Fortinet == Proxy-ARP
Juniper SRX == proxy arp unrestricted
Mikrotik == local-proxy-arp

As the Palo Alto firewall is one the best firewall in the industry, I hope that it supports this feature.

Any feedback is much appreciated.

Regards
