Proxy ID need and its requirement

[Vikashh]

Hello all,

I am new to Palo Alto and in learning phase. Why palo alto works based on proxy IDs? is there any limitation on this.

Please help.

Hello @Vikashh ,

Palo Alto Firewall supports route-based VPN.  If you want to form tunnel from Palo Alto to  other firewall which supports Policy based VPN, then proxy ID need to configure. Device that supports policy based vpn uses security rules or ACLs to permit interesting traffic via tunnel. Such rules are used during phase2 of tunnel  and are exchanged as procy IDs. And so proxy ids need to configure. If you are configuring tunnel between two palo alto firewalls, proxy ids are not required to configured as both are route based vpn.

Yes, there is limit on proxy ids. Article https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000Clc9CAC gives details on the same.

Hope it clear your queries!
