      I am not even sure the WAN side of things has internet. Should I be able to ping WAN hosts (google.com) from the CLI shell? because I cannot.

        Well yeah pfsense needs internet to be able to give it to clients behind ;)

        Does your pfsense show its wan up, it will tell you if it can reach its gateway, even if just your other router.

        You sure when you setup your lan 192.168.200 you didn't use a /16 mask did you? if your wan mask is /24 which should be common your lan should be /24 as well - if 16 it would overlap your wan and then yeah things would have issues.

          The WAN_DHCP gateway (192.168.100.1) is listed as online, then there is another GW_LAN (default) (192.168.0.1) that is offline.

            Well that is WRONG!!! you wouldn't set a gateway on your lan! I never understand how users do this - it doesn't ask you to do that... And even if you set one up, it tells you shouldn't

              In the LAN interface config, the IPv4 Upstream gateway is listed as "none", but I think I have more problems then that lol. If I can't ping internet hosts from the WAN. Also my LAN is 192.168.200.0/24 not 192.168.0.1.

                Post up your gateways... You shouldn't have any gateways other than your wan, which I assume you got from dhcp... Your sure pfsense wan is actually 192.168.100

                  Ok I deleted the 192.168.0.1 gateway. The only one now is the WAN which was from DHCP as you stated. It is listed as WAN_DHCP, WAN, 192.168.100.1 192.168.100.1 Interface WAN_DHCP Gateway.

                      can you you ping that? From pfsense

                      You can not ping say 8.8.8.8 from pfsense or you can not resolve www.google.com

                          what about 8.8.8.8

                          That 192.168.100.1 is your current router?

                            Correct, which would be the WAN gateway. Its actually a port off of a linksys LRT214 with its own vlan and subnet. If I plug my pc directly into that, I would get the same DHCP and have internet access.

                              Well if you can not ping 8.8.8.8 then you have something wrong with upstream.. Do a sniff on your wan while you ping 8.8.8.8 - do you see it go out??

                                From the shell when trying to ping, I get no route to host. Packet capture shows:

                                16:15:19 IP 192.168.100.100 > 192.168.100.1: ICMP echo request. id 2892, seq 3180, length 8

                                16:15:19 IP 192.168.100.1 > 192.168.100.100: ICMP echo reply. id 2892, seq 3180, length 8

                                  Then you don't have a gateway setup if you don't have a default route... Post your gateways, show your routes..

                                  Did you get your wan via dhcp, or did you manually set it?

                                    Ok, I put a USB NIC on this PC so I can copy and paste directly from pfsense. Yes the gateway was obtained from the DHCP. My routes are all weird:

                                      Dude why do you have openvpn setup... Get the thing working before you start trying to setup pfsense as a vpn client!

                                      And your not going anywhere without a default route..

                                        I was testing with no WAN, just using the LAN interface with openvpn, which did work just using the LAN. Shouldn't the default have been created automagically? Do I need to go System>Routing>Add and put a new static route?

                                          You have gateway set to auto? specifically set it to your wan gateway. Like you see in my post.

                                            That would be it. I am not sure why it was set to auto, I've been playing around with so many things before I was able to create my own little network to test the WAN.
