I have an issue with the "default firewall" rules that cannot be changed. According to the documentation, DNS requests originating from the LAN side will always be allowed. What if i wanted to restrict DNS queries (outside of the network) to ONLY say, OpenDNS, and disallow port 53 (DNS) for anywhere else? I am using OpenDNS to manage certain security settings for my network and do not want them to be able to be easily bypassed. This seems that their default rule for handling DNS requests is a big security hole that needs to be fixed (or at least allow experienced users to change it). I already have OpenDNS default in the DHCP setting, so the user would have to willfully change it..but I just want this extra layer of protection. Thank you.
