DMZ: function, special questions
by freewarehookie from LinuxQuestions.org on (#5FCAA)
Hello,
I am asking myself how a DMZ - demilitarised zone works.
And I have only a question in relation to: "routing", "devices" and firewallmanagement.
The questions are:
a) I read that its possible to use one network card with 2 IP ranges. Can you explain how that works? In my opinion I am only able to adress one IP adress to a specific adapter.
b) I read a concept with outer and inner firewall on a software basis. Can you explain that for me, please?
c) If I have two network cards and I want to route from one adapter to another, how do I configure that in Iptables? Don't I have to create a route outside iptables?
I appreciate your answers.
Kind regards,
Freewarehookie
