Problem with URL Filtering Order

Hello All,

 

I need a help in my case, i have a bunch of urls which must be permitted and any thing else must be denied. so i create a white list url using the (Custom Objects - URL Filtering) and then i create a URL Security Profile and blocked every categories and just alert my URL Filtering white list and then add it to my (Inside to Outside) policy.

 

The problem is here when i monitor the url filtering i found some of my urls are blocked beacuse it is exist in another categories like (Computer-and-Internet-info),  i think because of URL filtering order which describe that the order first for the blocked list then the allow list then the custom categories.

 

Any one face this problem before and if there any tricks to jumb over the order and mke this happen.

 

I tried to add my custom object directly to my policy and not to use the profile but in this case i can't know the url which will be blocked and in some times i need this to monitor my urls and to know if i need to open some more urls related to our network activity.

Hi @DerarAbubaker , do you have the same URLs configured in different custom URL catogaries, if so, please not that block have more preference than alert.

Please check if below document helps,

Please note that whatever url catogary you directly add to policy is a matching condition, it may not address your requirment

Hi @Abdul_Razaq  i have just one custom URL category but the conflicts happen between my custom category which have my white listed URLs and with the predifiened categories like ( Computer-and-Internet-info ) , i need to block all the predifiened categories and just permit my custom URLs to allow.

Hi @DerarAbubaker ,

 

Are you trying to allow any subdomains?. (eg. www.xyz.com/abc) ?)

For this granularity, you need to have decryption.

Hi @Abdul_Razaq thanks for your help, actually no because i have many subdomains for this domain and it will be many others in future so it is not a solution could i use even if its working. What about the decryption what do you mean of this? What should i do? and How could decryption help to solve this issue?

 

Another question how Paloalto firewall decide that this spacific non-public URL belong to that category?
