That's right, but my question was, Why do I need to set ACCEPT for INPUT/OUTPUT chains while all I want is FORWARD? - Why FORWARD seems to not function with dropped INPUT/OUTPUT? > Don't you need to assign a network card --- or at least an IP address > --- to each of the different OSs you're running on the same computer > before you can apply firewall rules to them?

Does my script do the very same thing?! For instance, -A FORWARD -p tcp -m tcp -m --state ESTABLISHED,RELATED -j ACCEPT -A FORWARD -i eth0 -p tcp -m tcp -d 192.168.1.1 --dport 80 -j ACCEPT -A POSTROUTING -o eth0 -j SNAT --to-source=192.168.0.2 -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.1.1:80 ? How I can do that not from scratch?! -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
