What do you think is the best way to integrate Dansguardian with Mikrotik? I only need to be able to filter web access from some of my clients. They are all on the 192.168.1.x subnet. I have currently only one LAN interface and one WAN interface, but I can add more if needed.
Thanks for your hint. I setup a DST_NAT rule just like you said and it works! My dansguardian works in a transparent mode and it does catch the http traffic that is redirected from my mikrotik box.
