DMZ would be another port entirely. This complicates the setup a bit, but isn't horrible. If you have ETH0 set for your WAN, and ETH1 for your LAN (e.g. 10.x.x.x) then ETH2 will be your DMZ.

so .. on eth2. would i add my first public facing ip address.?

That would be a common choice, and a good one. So yes. Not a strict requirement, but an easy way to go.

mroth911

what would be my gateway then for the /27..

JaredBusch

eth2 would have an address of X.X.X.65/27
then in your public faicng devices, they would have X.X.X.65/27 through X.X.X.94/27 and use a gateway of X.X.X.65/27

JaredBusch

That does not make it a DMZ< but jsut another network and everything will route back and forth.. You need to add firewall rules to restrict and such to make it a true DMZ.

Ok so i should remove the 10.254.254.1 off of eth2

and config the ip to 64/27

The IP that you assign to the router's port for that network.

Gentalman.. I thank you so much you guys rock!!! .... It is configured. and working!!!

mroth911

One last question... I put a static ip ...in my nic card... then I go on web ask what my ip address is and it's pinging the 242.network as my ip.. not the nic card i configured.

JaredBusch

It is going through NAT.

mroth911

I see masquerade eth0..

nothing with eth2

mroth911

it's not going threw nat at all? Wondering why eth2 is show ip 242 when i have the nic set to 66 .. Frustrating wish i new more time to learn! Thank you guys for all your help.

The traffic from eth2 is most certainly hitting the NAT masquerade rule.
