pfsense newbie here. I first learned about pfsense from a Network Chuck video on youtube, and decided to try it out for myself on spare hardware I had laying around. As best as I can tell, everything is working normally except that WAN is failing to pull my public IP, instead listing 0.0.0.0.

My setup is presently:

  • Arris SB8200 Cable Modem (COAX in, Two 1Gbs RJ45 out)
  • TPLink AX1800 Wi-Fi 6 Router (Presently servicing my home network, but the goal is for my pfsense rig to take over and repurpose the TPLink as an AP.)
  • pfsense build - Intel i7-7700K CPU, 1x8GB DDR4 RAM, Gigabyte Z170X-G6 Motherboard (this board has two 1Gbs Ethernet ports)

Both the pfsense rig and the TPLink are connected to the modem, but only the TPLink is pulling a WAN IP and able to offer web connectivity. For the sake of trial and error, I swapped the modem ports that each was plugged into, and tried each independently as well. In each case the TPLink would pull my public IP while the pfsense remained 0.0.0.0. I also called my ISP (Altice, so I wasn't holding my breath), and their reps said it wasn't a MAC binding issue because they don't control anything past the modem. According to the WebGUI, both the WAN and LAN interfaces are up, but I could really use help troubleshooting why the WAN won't pull an IP.

Best place to start is by going to Packet Capture under diagnostics select the interface and see whats going on. It looks like you only have outgoing traffic, probably a dhcp request and your not getting a response. Make sure you have setup a route to your WAN gateway and have it set under System/routing/Gateways. And add Gateways to your dashboard, if you set your monitor on your gateway to go to something close on the internet like 1.1.1.1 or 8.8.8.8 you can see your rtt and which will help in the long run. Also if you can't get a WAN ip directly try hooking a laptop directly to the Modem and see if it get's an IP.
