DMZ Setup for WEb sites

what you are contemplating is called NAT (network address translation) this can be done either via the router (no DMZ server required) or using routing and remote access in windows server (requires 2 network cards)

Hello David,

Thanks for the reply !, Could you please say what is the difference between NAT and DMZ, Why maxi IT companies recommened for DMZ server. this just an query as i am not much aware in DMZ Zone. thank you

which will be the best Nat or DMZ

Depends upon your point of reference
if you setup an ip as being in the DMZ Then all traffic from outside is routed to the inside IP
Port Forwarding (NAT) forwards traffic of a specific type on a specific port to a specific port on a specified inside IP

DMZ is a setting on firewall.
It doesn't matter what kind of software or service you're using in your network, DMZ it mean that ALL ports are open and forwarded to DMZ internal address.

THis is not to secure approach. It is much smarter to get information what ports needs to be open and create rules on your firewall to forward those ports to your web server inside network.
This will save you a lot of issues with hackers.

You can accomplish DMZ with NAT in almost ANY firewalls on the market.
If you talking about some industrial firewall and not expensive, I would suggest SonicWall
