how to whitelist Akamai downloads ?

L2 Linker

How do yuo configure a correct FW rule to only allow downloads for a specific user from a specific URL, but the content is hosted on akamai networks ?

 

I configred a FW rule with the URL of the server as FQDN in the destination field and allowed downloads but since the content is hosted on akamai, the FW rule is ignored.

I don't want to give the user full download access to akamai networks...

 

How is it done on Palo Alto FW's ?

Create a custom url category containing the needed url.

Then use it in the url category section of the firewall rule.

Use destination IP any.

The firewall will then allow the TCP handshake to any IP address and then when the first packet with payload comes it will compare the requested url against the url in the custom url category. If it matches, the session will be allowed. If not, the session will be closed.

Thank you for the information.

I've created a FW rule keeping your tips in mind and it works like expected now.

I have the same question for the trend micro update services.

 

nslookup show me the akamai dns adress e16632.dscd.akamaiedge.net

Is this the right one for the security rule?

 

nslookup smex125-p.activeupdate.trendmicro.com

I think i am missing something as my rule will not match traffic. I have created a custom URL category - akamai - with *.deploy.static.akamaitechnologies.com in its 'sites' list.

I then create a rule specifying the IP of my test machine (in zone trust) as permitted to reach any destination IP in the untrust zone. 

Applications is set to 'any'. Under 'Service/URL Category' i have 'any' service and URL category 'akamai'
