DNS failing to resolve.

Hi all,
I am running UTM 9.209-8 and am trying to use the web protection to monitor internet usage. My network is very simple (home usage).

Cable modem/router/DHCP -> UTM -> Cisco AP

The issue I am having is when I enable "web filtering" on to "Full transparent", the hosts/computer doesn't seem to be resolving the DNS. If I set to "standard mode", i have no issues surfing the web. I have tested this using the support->tools -> DNS lookup and it fails to resolve google.com on both transparent and standard mode

I have...
-both NIC's bridge
-DNS->Global -> bridged network interfaces added to the list.
-DNS Forwarders -> have tried google DNS and comcast DNS with "user forwarders assigned by ISP" checked.

I know I'm missing something small. I have googled, checked this forum and also read the Sophos KB.

Any help would be appreciated!

Hi

What does the DNS Forwarders option tell you when you select the "use forwarders assigned by ISP"?

What is set as DNS in you computers, Google or the ip address of the Sophos?

Hi Konkka,
DNS forwarders shows Comcast DNS. I'll have to check the second question when I return home.

Appreciate your help!

DNS on the computer shows comcast DNS.

I'm wondering if its not a DNS issue. If I set the web filtering operation to "Standard Mode", everything works fine. Only if I change that to "Full transparent", the browser times out and doesn't load.
