I have a Windows computer with IP Forwarding activated. However, I want to forward everything except the traffic that goes to port 53 in UDP. In Linux, this is easily solved with iptables:
iptables -A FORWARD -p udp --dport 53 -j DROP.
How can I do this with Windows? I think the firewall hasn't got the option of managing forward rules, only input and output.
Thanks for any suggestion.
