Hello,
I have to setup a firewall box for someone ASAP and I was going through the tutorials at
http://forums.debian.net/viewtopic.php?t=16166
I just have a small query as I am confused with the directions of packets. When setting a rule for the INPUT table, there is a source and destination setting. From the examples given in the above tutorial, when an incoming packet is received, the source is a local IP and destination is the world. Shouldn´t the incoming packet´s source be the world and destination the local LAN IP address? Could the experts please clarify? Otherwise it seems quite easy to setup.
