Did anyone every find a way to do this. Is there an iptables script/rule that would direct certain clients (mine and my wife’s) to my ISP’s standard DNS and let all other’s go to the openDNS DNS. Or frankly, the other way around would work as well . . .and would actually be better . . . let everyone else use the ISP’s DNS and point two clients (my 2 kid’s clients) to the openDNS DNS. THANKS!

I use opendns to block my kids PCs from bad sites (they hate me), but now I cant go anywhere on my own PC.

I don’t use the dns daemon onboard the dd-wrt, my dd-wrt router hands out IP addresses and the opendns servers via DHCP. static dns entry can defeat my filters.

I would like to hijack/redirect/forward port 53 traffic to openDNS servers (208.67.222.222 & 208.67.220.220), unless it is coming from my PC (192.168.1.100) then I want it forwarded to my ISP dns (unfiltered).

I would also like to block outbound WAN traffic on any port other than 80, and 443 because one day they will figure out how to proxy or vpn out.

Can anyone help me compose the iptables rules?
