How to configure firewall for server with public IP?

HelgeP

Hi,

I have a few public IP adresses and I want to use just one IP for a server behind port3 of the XG86 firewall. port2 should be WAN and  port1 is used to manage the firewall.
I don't want to assign the firewall any public IP, it only should have assigned private IPs.
The traffic of the server behind port3 should of course be filtered by the firewall itself.

I have already tried a WAN(port2)-DMZ(port3) bridge with a private IP, but the server behind port3 didn't get any internet access with that configuration.

Does anyone have any idea how to set this up correctly?


Best regards,

Helge P.

    Hello  

    If you have configure bridge between WAN(port2)-DMZ(port3), you will still need DMZ to WAN firewall rule without any NAT policy.

    and assign public IP address manually to your server.

    Further the line: "I don't want to assign the firewall any public IP, it only should have assigned private IPs." is confusing because for other users(apart from server) in network, how do you provide internet access?

    Hi Hardik_R,

    thank you for your answer. There is and there will be only one server behind the firewall.

    I have added a firewall rule for dmz to wan (without nat), but I cannot get it working with only private IP on the bridge.

    When I assign the bridge a public IP, the server behind gets internet access, but I don't want the firewall to have any public IP.

    Have I configured something wrong?
