Capture default gateway IP

[DeonB]

I would like to capture users using 192.168.1.1 which is my default gateway and DNS. The idea is to force some users to use OpenDNS. Any ideas on how to do this? I have not been able to formulate a rule to achieve this.

do you mean "block?"

I think the firewall app is better for this.
You can create a firewall rule to block all port 53.
Then just above it create a rule that allows port 53 traffic to the servers you allow.

I want OpenDNS to do the blocking. I want Untangle to tell the user if he is using the wrong DNS.

Then you need to just block other DNS servers.

You can't "capture" users based on what DNS/gateway they use. You can only capture based on IP.

Thank you. I will try using the Firewall.
