      LAN 127.0.0.0/8 ::1/128 * * 500 LAN address * Auto created rule for ISAKMP
      LAN 127.0.0.0/8 ::1/128 * * * LAN address * Auto created rule

      That is Never going to work!!! Where is your local network? 10.0.0/24

      Here is mine just setup

      You got something broke if its not creating the automatic NAT for your lan network.

      You set a GATEWAY on your LAN interface didn't you to what its OWN address... Pfsense clearly NOT to do that!!!!

      GW_LAN LAN 10.0.0.1 10.0.0.1 Interface lan Gateway

      How could you think that would work???

      I just went through the wizard again... It doesn't even give you a option to set the gateway on the LAN... You have to go OUT OF YOUR WAY to do that... And then NOT read the info that clearly says NOT to set a gateway if its the local network and not your wan..

          Sorry but NO its not the pfsense image..... Out of the box the IP Lan for pfsense is 192.168.1.1/24 with NO GATEWAY.. For it to be 10.x.x.x you had to have changed it... It sure and the F would not have set a gateway to itself.. It just wouldn't!!! Its NOT possible.. You saw my setup, I just ran through it in like 5 minutes... The longest part was downloading the quick VM for ubuntu in hyper-v ;)

          Did you download this image of pfsense from somewhere other then pfsense/netgate? Is it some hyper-v image you got from somewhere?

              Huh? Dude grab the current ISO from netgate and install it and you will be up and running in 5 minutes.

                      @derelict johnpoz most likely got the solution right. on the LAN interface the ipv4 upstream gateway should've been none. but I got a fresh iso and did an update and had another fresh start with default configs and paid attention to make sure not to put anything in the upstream gateway. I was also able to figure out a number of other issues why the dc acted weird. it was all networking related. lol

                        It never even ASKS you for that in the gui wizard... And if you do it at the console it clearly states NONE for lan. You really have to go out of your way to mess it up like that! ;)

                        How would the gateway be its own freaking IP... See this error quite a bit over the years - and it never makes any sense what someone was thinking when they do that..

                        Glad you got it sorted - another one to chalk up to pebkac ;)

                          @johnpoz just for learning sake, if this was a cisco router, how would one set the NAT? anyone happen to know the command? is it

                          enable
                          configure terminal
                          ip nat pool name start-ip end-ip {netmask netmask | prefix-length prefix-length }
                          access-list access-list-number permit source [source-wildcard ]
                          ip nat inside source list access-list-number pool name
                          interface type number
                          ip address ip-address mask
                          ip nat inside
                          exit
                          interface type number
                          ip address ip-address mask
                          ip nat outside
                          end
