I installed a machine with Redhat 8 and are trying to set up a iptables firewall with 2 internal segments (DMZ and internal network). My machine have 3 Network cards. Is this possible ? I can seem to get all the segments to see each other. Can you give me an idea on how to do this. Is it just a question of routes / Nat and Arp entries ? DMZ - 192.168.1.0 / 255.255.255.0 Internal Network / 192.168.2.0 / 255.255.255.0 For the external interface, I have 64 ip addresses - 255.255.255.192
