I'm Sorry - Basic Question - no Internet

[former]

I'm absolutely new to OPNsense. I just purchased a Protectli FW4B and it came installed with OPNsense 20.7. An update was performed, it's now at 20.7.7_1.

It's a basic setup. Xfinity router providing DHCP>(WAN)Protectli FWB4>(LAN)computer. The computer cannot get an IP when connected this way.

Nothing is passing through OPNsense. The Xfinity router is 10.0.70.1; OPNsense WAN 10.0.70.74; OPNsense LAN 10.0.70.75.

There is an unmanaged Netgear switch. When both WAN and LAN ports are connected to it. The computer gets an IP. But that's not the way the firewall is supposed to work.

The Wizard was used to set this up. The only change other than IP's was enabling DHCP Relay. But either way it's not working. I know this is probably something simple. But I'm just not seeing it yet. The guides and videos referenced for setup just appear to work. Mine doesn't.

Once this single computer is working, the Protectli will be connected directly to the Xfinity router.

Thanks

ok, I found out the ports are flipped. The LAN is external, the WAN internal.
