Title: OpenDNS and Firewall Rule to Block other DNS traffic
Post by: ggalt on April 11, 2016, 08:13:45 pm

All:  I'm new to Opnsense and so it may be that I'm missing something simple.  I'm trying to follow this guide https://www.kirkg.us/posts/using-opendns-with-opnsense/ (https://www.kirkg.us/posts/using-opendns-with-opnsense/) to prevent other users (my son) from bypassing OpenDNS.  Specifically, the guide sets a firewall rule that prevents all traffic on port 53 (the DNS port) from computers inside the firewall.  The destination domain to which the rule is applied is called "this firewall".  AFAICT, this was used in pfsense and earlier iterations of OPNsense, but that option is no longer available.  What does appear to be available is an option of "WAN net".  Is "WAN net" the correct destination domain for this rule?

Thanks,

George

Hi George,

Since you're trying to pass local queries along, I think LAN address (if your interface is LAN) is the one you're looking for.


Cheers,
