Hi!

firstly, so glad I found this forum, was disappointed to see ITUS go down the gurgler.

e2Guardian does have a few issues, particularly with performance on the shield.

I changed over to using OpenDNS which allows for the same level of blocking at a DNS level, no load on the Shield, and then use DDNS with DNS-O-Matic to update my dynamic IP so the custom rules I apply follow.

All I have to do now is figure out how to intercept all DNS and forward to OpenDNS incase a local client decides to use a custom DNS eg 8.8.8.8 and therefore bypass the blocks :)

I am pretty sure I can do this with a firewall redirect in iptables.

#Redirect DNS requests to go through router
iptables -t nat -A PREROUTING -i br-lan -p udp --dport 53 -j REDIRECT --to-port 53
