Dear Sir/Madam,

I have read theories about DMZ. How do I implement it?

I have the following:-
1 router, 1 FW (2 x NICs), 2 x Internet Servers(mail+www), other PCs are local

Internet IP: 14 Usable (x.x.x.161-174)
Local IP: 192.168.0.x

Is this setup correct?

intenert --> router (WAN IP 161) --> (WAN IP 162) fw (LAN IP 192.168.0.1) --> switch --> local PC
from same switch --> internet server 1 (192.168.0.2)
from same switch --> internet server 2 (192.168.0.3)

On fw - do portfw 163 --> 192.168.0.2 (for www, smtp, pop)
On fw - do portfw 164 --> 192.168.0.3 (for www, smtp, pop)

Is this called DMZ?? Or how do I setup one with the above devices?

Appreciate any suggestions.

Thst is a VERY theoretical DMZ most people create physical seperations between the LAN WAN & DMZ as below.
