The router board 150 has 5 ports I have 2 in use one WAN and one LAN. My ISP provides me with 2 dynamic IP address. One is being pulled via dhcp to my router as my main internet on port 1 (WAN).
What I would like to do is make port 3 as DMZ and if possible make what ever device connected to port 3 pull that 2nd public IP address.
could just bridge it, and let it get your IP from your provider. No biggy their. Then you can use the IP Firewall with your bridge (in v3 make sure to check the box), to create your firewall rules.
That kinda worked. I made a bridge and associated my WAN port to it and my port 5 as well. But as soon as the bridge is activated my main internet stops working and the internet on port 5 gets an public ip address and it works fine. As soon as I disable the bridge my main internet works and it doesn’t on port 5.
