Ultimately the new firewall was a success and we continued to use the modem's NAT features to route all the traffic to the new firewall and proceeded to decommission the old firewall.

It sounds like you are over-complicating things. You should be able to just configure the new firewall with the IPs you want to go to it, then remove those IPs from the old firewall. Which IPs go where should be handled automatically by the ethernet layer.

We are having the same issue with Comcast biz modems. It seems the SMC is doing packet inspection and that is causing the issue. Sooo its not working properly. Sign up to join this community.

UPDATE Our solution was to just build and configure the new firewall, plug it into the modem and then log into the modem's web interface and use it's built-in NAT which has a fairly clunky interface to direct traffic accordingly during the testing phase.

It is important to setup a static ip address in the device that you are forwarding a port to.

This ensures that your ports will remain open even after your device reboots. Your router has a web interface, so you will login to it using your web browser. It usually does not matter which browser you choose to use. Open up your web browser and find the address bar. It should look something like this:. Above is an example of what a web browser address bar looks like. Find the address bar in your router and type in your router's IP address.

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:. Now we need to find the port forwarding section in your router. Here's how you do it.

Starting from the first page in your router:. You need to name this entry in the Application Name box. The name does not make any difference in the forward; it's just there so that you can remember later why you setup this forward. If you are forwarding a range of ports, enter the lowest number of that range into the left hand Port Range Public and Port Range Private boxes. If you are forwarding a single port, enter that port number into both of the Port Range Public and both of the Port Range Private boxes.

From the Protocol box select the protocol for the ports that you want to forward.
