@kom So when I factory reset the router with pfsense on it, for some reason it reset the port assignment so that the port labeled WAN on the device was not the actual WAN port anymore. The LAN/WAN ports went from being assigned to ports igb1/2 to igb0/1. On top of that, the way the ports were numbered and labeled is not very intuitive (at least not to me)
It basically goes like this:
First port: labeled LAN, (igb1)
Second port: labeled WAN (but not WAN) is (igb2)
Third port: (ibg3)
Fourth port: actual WAN port on factory reset (igb0)
So the "0" port is the 4th port and is, of course, not labeled WAN but became the WAN port upon factory reset.
I did not think igb0 referred to the 4th port or that the factory reset reassigned the ports. Once I finally figured that out, it was simple. Like I said, I am pretty much a noob, but there you have it. I was finally able to get pfsense up and running with the VPN, added wireless, etc after that. It's no wonder everyone was so stumped.
