      " in ifconfig the LAN shows as "re1" but in the main menu it shows as usbus0… not sure if that matters?"

      Can you show us your pfsense interfaces, under status

      if your not getting IP from the dhcp server running on pfsense - yes this points to problem.  So your manually setting IP on your PC, when you try and ping the pfsense lan IP, and then look in you arp table

      arp -a

      Do you see anything for the pfsense IP?

        I cannot show you the pfsense interfaces because I cannot access the webgui, because I cant communicate with LAN. So as you said, I plugged my PC into the LAN in pfsense, and manually assign (because DHCP is not working apparently) and IP in the same subnet as my lan, using the same mask, and the LAN IP as the gateway. I still cannot ping the LAN ip, or access the webgui. ARP table shows nothing for pfsense. I did a little troubleshooting from the pfsense box itself, which yielded something interesting.

        First, I pinged my mode, which worked fine.
        Then I pinged Google (8.8.8.8), that worked no problem.
        Then I pinged my LAN IP which worked fine.
        Then I tried pinging the PC that is connected to LAN, and the system kernel panicked.
        So I tried again… same result. Anytime I try to ping through the LAN interface, a kernel panick... I hope someone has an idea :(

          another update… apparently the interface was not going up by default so I had to "ifconfig re1 up"
          and after that, there was no inet address so I had to "ifconfig re1 172.16.0.1 up"

          still does not work though.

            Im starting to think I have an unsupported NIC (DLink DGE-530T) and this can't be resolved, which is awesome.

                I can now ping anything on the LAN subnet from the pfsense box, but not the pfsense box from the LAN subnet.

                My arp table is as follows:

                
                C:\Users\Aaron>arp -a

                  172.16.0.1 is the pfsense LAN IP, and that is the correct Mac address for it, but I still can't access the web-interface

                    What is the FreeBSD device name for your LAN device? (displayed by shell command```

                    /etc/rc.banner

                    
                    What version of pfSense are you using?
                    
                    Your arp table shows entries in the 172.16.0.37/x subnet but your pfSense LAN IP address is 192.168.1.1.  How does the system whose arp table you displayed get to the pfSense LAN interface?

                      Sorry, my pfsense LAN IP is not 192.168.1.1 anymore, i had modified it to 172.16.0.1 for later avoidance of VPN issues. I thought I had mentioned that but must have forgotten.  I am running the beta version as this was the only version to even detect my NIC. The LAN device is labeled "usbus0"

                        Did you reboot after changing the LAN IP address. It has been my experience that a reboot seemed to me necessary after changing subnet of interface.

                        So you are using a GigE device for your WAN interface and a USB NIC for your LAN? Strange choice! It is  while since I used a USB NIC, but I have a recollection the device name of USB NIC was something like ue0, udav0 etc not a name of an I/O bus. Please post the output of pfSense command```

                          Resolved…
                          added hw.usb.no_pf=1 to loader.conf file. The issue was with my interface being given two names by pfsense, and neither being configurable.
