      I changed the iPad’s LAN to 192.168.3.0/24 and still can't browse the LAN behind the pfSense OpenVPN server. I can only access and ping the pFSense box and use pFSense web interface, but I can't ping any IP address of the LAN.

      pfSense 2.3.2-RELEASE-p1 (amd64)

        What do your Firewall rules look like on the OpenVPN tab?

          The OpenVPN Tab under Firewall –> Rules was created at the end of the OpenVPN wizard, so is reporting an allow any rule.

            What do the firewalls on the HOSTs your trying to ping look like..  This is such a common issue!!  Out of the box windows for example is not going to answer ping from different network.  What firewall profile are you in, private public?  Same goes for linux running local firewall.

            edit:  Would show you a picture of the windows default icmp rule - but seems attachments not working

            here I will link to it

            When pinging other type devices like camera's do they even have a gateway setup..  Can not ping something from a remote segment if doesn't know the gateway to get off its segment.

              I found the solution!  ;D

              Here is my new server.conf. I simply added

              route 192.168.20.0 255.255.255.0
              

              in the Advanced configuration box of the OpenVPN configuration.

              Then I enabled in System: Advanced: Firewall and NAT

              NAT Reflection mode for port forwards –> Enable pure NAT

              and (in System: Advanced: Firewall and NAT too)

              Enable automatic outbound NAT for Reflection –> Automatically create outbound NAT rules which assist inbound NAT rules that direct traffic back out to the same subnet it originated from.

                Glad to hear you're up and running  :)

                Interesting note about needing to set NAT reflection, that's not something I would normally have suggested with OpenVPN.  The "route 192.168.20.0 255.255.255.0" option also doesn't look like a typical req't.

                My experience has been that the OpenVPN "Road Warrior" type installs are pretty easy.  Normally the biggest issues are with getting the certificates setup correctly.

                How did you install the client on the iPad?  I usually install the OpenVPN client export package to make sure things get setup on the clients properly.

                Anyway, I'm not one to argue with success!

                    You clearly do not need to route your tunnel network.. So that is not fixing your issue of no ping..

                    You do not need nat reflection - so while you think you fixed something with those setting..  They have nothing to do with what your original issue was - its more likely the restart of the openvpn service fixed the problem vs those settings.  They have nothing to do with using vpn – they are not in your guide you linked too that is for sure ;)

                    I don't have them setup and I access and ping resources via a vpn connection pretty much every single day.

                    Just Saying ;)

                      I've just disabled

                      route 192.168.20.0 255.255.255.0

                      restarted the VPN and… it doesn't work anymore. Put it back in and... it works.

                        Try this - Just list it in "IPV4 local networks" along with the other /24 you have listed there and remove your push command.

                        I wonder what that would do?
