DNS Proxy

L2 Linker


i wanna achieve dns proxy wherein my requirement is as follows:

1. i wanna use my internet browsing PCs to use palo alto defined DNS which will use our ADSL 100mbps connection for browsing.

2. secondly, my other critical PCs will use DNS from existing AD and use Lease Line internet for server access and mission critical tasks.

i feel i can achieve this via dns proxy feature in PAN , but little confused how to go abt it.

appreciate help




Whatever configuration that we are discussing is related to DNS traffic only. As per my understanding, this shouldn't affect your group policy updates from DC etc. For that your system should be part of domain that's it and there should be reachability between PCs and DC.




I will check and let u know 

 Thanks mayur for ur insights.

@zaidshaikh ,


I think, you are mixing two things, group  policy push and dns functionalities.



Yes. just now i tried the putting my PC with this new interface IP, am able to resolve dns names also my PC is effecting changes via domain and dns.

Thanks BK and Mayur for making me understand.


Now the problem is the same with DNS proxy(ie PAN) also, am not able to resolve any internal URLs (like 172.16.60.X:8888) to resolve i want to know how to add/or put ports insode the DNS proxy rules inside PAN.


Thanks Guy:)



Have you added DNS proxy rules?

Under DNS proxy rules, you can add internal URLs  and under domain name section (without port) and internal DNS servers under Primary and Secondary tab. With this, PA firewall will forward mentioned domains to mentioned dns servers. Just make sure, there is reachability internal DNS servers IPs.


The other way is to add static entries. Under Static entries tab, enter FQDN and it's associated address.


Hope it helps!




Yes i added both dns proxy rules and static entries.


But inside the static entry page also the address need to mention for a fqdn also is only taking ( 172.X.X.X) NOT (172.X.X.X:8888)

i wanna achieve the latter part of this.





Why do you want to add port? It will only accept IP address not port.




becoz there are servers internally which is running on different services.

otherwise all is working fine. but i cannot move forward if other teams are not able to access these servers for their activity.





You can't add port in this settings, firewall will not allow to configure same.


Also your requirement should be fulfilled without adding port. If you are using DNS proxy rule, you just add DNS server IP against the internal URL. And under static entries, you just need to mention URL against its associated IP. For this, it is not required to configure service port, it should work properly.




Yes you are right.

Becoz we understand is that the dns proxy is doing its job by resolving the URls to IPs configured in the DNS-Proxy.

About Port issue i believe it out of this topic..
