Norton ConnectSafe not working

I have set up ConnectSafe according to the instructions on the web site and it does not filter anything.

What I did:
- Checked the IPv4 and IPv6 settings on the network adapter to ensure they are set to obtain DNS addresses automatically.
- On my Asus RT-N66R:
-- Under LAN settings, DHCP Server, DNS Server is blank.
-- Under WAN settings, DNS Server 1: 199.85.126.20, DNS Server 2: 199.85.127.20
-- Applied the settings

- Restarted the cable modem, router and flushed DNS cache on computer

- ipconfig /all lists DNS address as my router (which I assume is correct)

Neither IE, Firefox or Chrome block porn.

I have turned off google's URL suggestion service as well, but to no avail.

I have also tried setting the DNS servers directly on the network adapter, flushing the cache and it still does nothing.

What am I missing?
