Will FQDN names work when the name resolves to a content delivery service?

For example:

www.microsoft.com.      1937    IN      CNAME   toggle.www.ms.akadns.net.

toggle.www.ms.akadns.net. 20    IN      CNAME   g.www.ms.akadns.net.

g.www.ms.akadns.net.    20      IN      CNAME   lb1.www.ms.akadns.net.

If you were allowing access to www.microsoft.com, wouldn't everything that these akands.net devices being allowed?

I dont know how roundrobin dns names are handled in the PA.

But regarding address objects containing FQDN instead of IP the FQDN is resolved during commit and then there is a script that every 20 (or if it was 30) minutes will recommit the FQDN portions to keep them up2date (because in the fabric only ip addresses are being handled).

In you case (if possible) you could add an url filter aswell if you only want to allow requests towards www.microsoft.com.

Well, my problem is that we are using authenticated access... Certain users groups have rights to access more URL groups than others...

How would I create a URL filter to allow un-authenticated access to www.microsoft.com while continuing to require authenticated access for the other type of URL groups?

Any help on this would be greatly appreciated!!

Well you can use a security Policy before all others

with a Custom URL Category as match Object and allow traffic through this Rule (supported since 4.1.x)

Like this:

Kind regards


That would be great if we were running 4.1... We're still on 4.0.12 at this point... With 17 firewalls and Panorama, upgrading is somewhat painful..

Panorama should make that easy. Smiley Wink
