Cisco 881 Zone Firewall issues

martinbuffleo — Tue, 12 Mar 2019 01:15:19 GMT

I'm having issues with an 881 that I have configured as a zone based firewall.

I have allowed HTTP(s) and DNS on the DMZ but my user is saying he cannot access the internet.

On the corporate side the user complains that some websites fail, such as Linked in.

I have been using CCP to configure the device. What am I doing wrong?
