Palo Alto is not reading full URL

[Shuaib_Khalid]

We have an in house mail server which have different URLs to access its web mail and administration center. We want to block administration center access from Internet. I tried using URL Filtering but Palo Alto is not reading full URL and only showing host name in URL Filtering logs, I have also imported the the email server ssl certificate on Palo Alto but still same result. Although it is showing full URLs for outgoing web traffic.

Please help in this regard.

Hello,

If I understand correctly, you are attempting to use URL filtering for inbound traffic. I would say a custom URL category with the full URL and applied to the policy should work.

@Shuaib_Khalid,

I would hazard a guess that you are decrypting outbound traffic and you are not decrypting inbound traffic. If you aren't permorming decryption on the traffic, the firewall is only going to see the base URL. You either need to block this access through your mail server or start decrypting the inbound traffic so the firewall can see the full URL.

Hi There,

Inbound SSL decryption worked for me, now PA is reading full URL and i have blocked Administration Center URL via URL Filtering. 

Thank you so much for help and guidance.
