I am trying to elminate my ISA 2006 server and use url filtering. The setting to use the ISA server were applied using a GPO that sets the internet options/connections to user the proxy server. I modified the GPO and have confirmed that the internet options setting was removed from the users pc's. But the users are still going to the old proxy server, what is the best way to check to see what might be sending them to the proxy server and if its the PA that is routing them there still?
What happens if you use a browser like Firefox that is not beholden to the GPO (unless you are using a Firefox ADM file) ensuring that the connections settings is set to "No proxy"
We were using TMG 2010 prior to switching over to PA. It was a great change, but I do miss a thing or to about ISA/TMG.
Standard GPO is for lack of a better term is ignored by Firefox. Chrome looks at and grabs the settings in "Internet Options" in the control panel by default, so I find Firefox to be a better way to test and troubleshoot weird issues like this.
There is an ADM/ADMX file that you can add to your domain controllers and manage Firefox much like you can manage IE from a GPO standpoint. As long as that had not been done in your environment, the Firefox settings are set to "No Proxy" and there is nothing like the ISA Firewall Client installed on your PC's that is intercepting and tunneling traffic to your ISA Server, then all traffic from that PC "should" follow your standard TCP/IP routes and all traffic, web and otherwise will go through your Palo Alto Firewall and URL filtering will be applied to all traffic where the policy on the PA applies your URL Filtering Security Policy.
