Hi,


I must replace a SMC router with a slack server.....but I have a question about nat and routing
my scheme will be like this
1 public ip and a subnet with 8 ip`s routed through first ip


eth0 - interface with internet
eth1 - dhcp 192.168.0.x-
eth2 - dhcp 192.168.1.x-
eth3 - dhcp 192.168.2.x-
eth4 - 80.86.x.y - this must be a DMZ and ip will be the first from subnet


i have a voip modem and require many forwarded ports......it`s more simple to put in a DMZ....this modem will have next ip from subnet like 80.86.x.z

now....i use jay iptables firewall and doesn`t have a option with DMZ.....when I will activating ip_forward i will seen voip from internet?.......firewall for eth0 will block access to 80.86.x.y?.....i think no

thanks and excuse my poor english

Well one way that I can think of it, make routes to each of those ips like

/sbin/route add -net 192.168.1.0 netmask 255.255.255.0 eth0
/sbin/route add -net 192.168.2.0 netmask 255.255.255.0 eth0
/sbin/route add -net 192.168.3.0 netmask 255.255.255.0 eth1
/sbin/route add -net 192.168.4.0 netmask 255.255.255.0 eth1

Modify the above command to suit your needs.

Sorry if I did not answer your question.
