On my ADSL router firewall configuration there are 3 interfaces - Public, Private and DMZ and one can apparently specify ALL.
I understand Public as the Internet side, Private as my home LAN side and I don't really understand DMZ for which there are default rules set up.
I have my single port router (Ethernet) connected to my main computer, which has two ethernet ports, on eth1. The home LAN is connected to the other ethernet port eth0. This computer masquerades for the other computers on the network.
Do I really need the DMZ rules?
At a *VERY* rough guess I'd say the the "DMZ" sets up the rules for traffic forwarding etc from internal to external and vice versa, the equiv of ipmasq and family. You'll probably find if you kill the rules the outside will disappear to you.
