      @derelict yes.... but why doesn't it have internet? If I use the same external network adapter in a windows 10 vm it has access to the internet.........i'm accessing the web gui via the LAN address which is 10.0.0.1 /24.... not from the 192.168.1.x interface. It's updated to version 2.4.4.2... i don't get it...... how does it not have internet but able to download and update? LOL

      The process will require 24 MiB more space.
      [1/1] Upgrading pfSense-kernel-pfSense from 2.4.2 to 2.4.4_2...
      [1/1] Extracting pfSense-kernel-pfSense-2.4.4_2: .......... done
      ===> Keeping a copy of current kernel in /boot/kernel.old

      Removing unnecessary packages... done.
      Upgrade is complete. Rebooting in 10 seconds.
      Success

      nvm it has internet...i got the package list after the update

        ok so if it has internet - then you clients behind it would have internet.

            Can clients ping pfsense IP? Is this what is set for their gateway?

            Lets see a traceroute to 8.8.8.8 for example

            First hop should be pfsense IP on your VM lan you setup. Do I really have to fire up hyper-v to show you how simple this is?

              can ping 10.0.0.1 (LAN interface), 192.168.1.11 (WAN interface) fine no problem with no loss
              can not ping 192.168.1.1 which used to be the ASA FW, which I am now putting in a normal Netgear Nighthawk hoping it wasn't the firewall.

              After doing a tracert looks like it don't know what to do with the traffic from 10.0.0.1? This is what I get:

              C:\Users\User>tracert 8.8.8.8

              Tracing route to 8.8.8.8 over a maximum of 30 hops

              I would like to note a couple things though before I leave for work:

              edit-
              also want to mention I realized Hyper V created this weird Default Switch which is greyed out it state the Default network switch automatically gives virtual machines access to the computer's network using NAT. Any idea if I should be doing this for anything? When I look at it from the host it has a 172.18.19.255 255.255.255.240 network.

                And you did a clean install of pfsense with a wan and lan switch in hyper-v?

                Here this is how freaking drop dead simple this is..

                Created my wan external switch, connected to nic on my host machine.
                Created an internal vswitch (only for vms)

                Did a pfsense vm, 2 nic 1 on wan switch, other on lan switch. even set my lan IP to be the same as yours 10.0.0.1/24

                Fired up test vm on the internal switch.. It got IP from pfsense dhcp, can access the gui, internet.. If it takes you more than 5 minutes to set this all up you have something wrong..

                You can see pfsense sees there is update available - so it can get to the internet.. client can get to the internet through pfsense.. See the traceroute.

                  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

                  0_1548851556596_outboundnat.png

                  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???

                  0_1548851859050_lannogateway.png

                  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.

                                For posterity, do you know what the solution was?

                                  @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
