DynDNS Filtering Issue

Hello all,

We are using the free stuff...

Is anyone using DynDNS for web filtering? We have it for our public network and for some reason it won't filter. It allows access to all areas (the risky ones too).

Cisco wireless controller.

DNS is properly pointed to their systems and if you visit http://setup.dynguide.com from a user connected to the public network the pages says everything is a OK.

Any ideas?

Thanks,
