Palo Alto Forward Proxy?

L4 Transporter

We presently leverage a fwd-proxy solution that a selection of hosts (2000-3000) on various networks pass through in order for us to funnel them to a few IP's and enforce a more STRICT URL policy at the perimeter. The hosts are managed through GPO.


My question is will PAN or has PAN developed the capability to take the role of a fwd-proxy server that hosts can be pointed too so Internet connections are funnled to a specific interface or similar like this type of scenario? 


Thank you

Hello @Gun-Slinger,

I think it would help the community out if you explain exactly what your current proxy is doing, just logging, captive portal, ssl decrypt etc. With the PAN you can funnel all of your traffic out one interface, or more in case of failover for upstream issues. The more detail you provide (obiously redact any info that can used against you) the more we can help out.



Do you mean that your devices are behind proxy server?

In this case your proxy server should add X-Forwarded-For for Palo to identify UserID and apply Security Policies and profiles based on user/group.


Palo itself is not proxy. It does not cache or do url rewrites.

To clarify, we use a fwd-proxy environment that hosts through GPO are pointed too (See example from IE):


This proxy strictly just completes a fwd-proxy on 2000-3000 hosts on subnets across the institution. No other services are performed on this proxy.

The 2 proxy servers are and for this example. Our Pan URL filtering is at the perimeter and these 2000-3000 hosts require a more strict URL filtering profile then the other traffic in the istitution. In order to do this without adding every host to the policy with this URL filtering profile, we point through GPO (see above) to the 2 proxy servers that then proxy the connections behind or 9.9.

From there our policy on the perimeter is built to apply the more restrictive URL filtering policy to these 2 IP's and 9.9 which in turn is applied to those 2000-3000 hosts.

The question is if this proxy function can be obsorbed into the PAN? Where we could point through GPO the hosts to an interface on the PAN and from there it is treated like a proxy but a point we could apply specific URL filtering profiles too.

Thank you for any guidance.


Ah the old URL filtering and who gets the more strickt one. So with reference to the GPO and pointing to a proxy, that piece would be removed. Then you would have security policies on the PAN for the different levels of URL filtering. My personal favorite way is to use AD groups. For this you would have to setup the user-id feature set, either agentless or with the agents or both. This way we can just add and remove users without having to touch the firewall. Another methow could be source subnets or zones. 


i.e. you have a URL filtering policy 'More Strict URL' and assign a AD group to it. That way no matter which machine or where the user is located, they are always in the More Strict URL filtering group. 


Here is the link to the general guide for PANOS8


I hope this makes sense. Please feel free to ask additional questions.

The firewall does not perform web-proxy services


a different approach however could be to leverage User-ID and create policy based on group membership or on the fact a user has been/has not been identified

Thanks @OtakarKlier and @reaper for the feedback. I had forgotten until it got mentioned, but originally I went the user-id route as these machines use a resource account across all of them which made it very easy. This worked well until a desktop admin logged in to the machine to work on an issue and it would override the machine allowing the machine to now bypoass the more restrictive URL filtering process. The option was looked at to ignore these admins but the list was very long and used in other User-id rules. This is why we had to go the proxy route.
