I just didn't get around to it till now. Was working when I ordered it. I had plugged it in and powered in on, and both link lights were on when I plugged a cable and I was able to get pfsense installed, just didn't get around to actually setting it up till now. This is really such a weird failure that it took a whole day of wasting time troubleshooting.
I can't do static on WAN, my ISP does not provide static IPs (I WISH. It would solve a lot of my other annoyances such as having to update firewall and other rules on my web server each time my IP changes).
When I switched the interfaces so that the "bad" interface is LAN, it was static but it was not passing TCP/UDP traffic. I could ping it, but could not do anything else.
I'm back fully connected to other firewall now. In this process I was also able to bypass the Asus router that was being used to do pass through. It was needed when I had TV service as the way TV service is provided is really weird, so that router has a custom firmware specificly for my ISP. But now that I only have internet I just had to setup WAN interface to use vlan 35 and I can plug straight into the ONT.
But yeah this blows, wasted my day on this, not to mention my money. Now to figure out what to do with this thing. I hear Photonicinduction is going to be making more videos soon.
