      Hi,

      I had configure a OpenVPN in tab mode (Bridge). I follow this manual : https://forum.netgate.com/topic/42698/how-to-openvpn-tap-bridging-with-lan

      Everything work fine, the remote client connect well, DHCP is Assigned well, I can ping the Lan and Wan interface, but I can't ping the host in the Lan network.

      I add a "permit all" rule in the firewall on the Wan, Lan and OpenVPN interface, but even this don't have connection to the host in the Lan.

      The bridged is with the Lan interface.

      Any help please.

        I understand that you are testing, but a "permit all" on WAN is bad, very bad.

        As told in the Official pfSEnse Video's, "bridging" is possible, but tricky.

        Can you ping your host (what host ? where ?) from pfSense, using the console menu ?

        The default LAN rule works just fine - what did you change ?

        No "help me" PM's please. Use the forum.

          Hi, thanks for your reply.

          I know a permit all is a bad idea, but just wand to make this work.

          I install the OpenVPN client in a Windows PC (this PC is the cliend that will connect to the pfsense OpenVPN server. It is outside the pfsense networks), import the ".ovpn" downloaded form the pfsense, and I connect to the pfsense OpenVPN server via the pfsense Wan interface. From the Windows PC I can ping the Wan and Lan interface of the pfsense, but can't reach the hosts on the pfsense Lan side.

          Thanks...

            Can you open the pfSense GUI using its URL or http://192.168.1.1 ?

            ipconfig /all

            On your connected PC says what ?

            OpenVPN client log ?
            Open VPN server log ?

              You mean if I can open it form the windows client when I connect to the VPN. No, I can't. The Ip is 172.16.1.1. I can Ping it but can't access http. In the local 172.16.1.x I can access http, this the way that i configure the pfsense.

                    Hi Rico,

                      Question :

                      @hunteralberto said in Can't reach Lan host in OpenVPN tab mode:

                      Description . . . . . . . . . . . : TAP-Windows Adapter V9
                      .....
                      DHCP Server . . . . . . . . . . . : 172.16.1.0

                      A DHCP server living on an IP ending with 0 ?? That's new for me.

                      No "help me" PM's please. Use the forum.

                        Yes, this is so weird for me too.

                        I set the DHCP setting in the "Server Bridge DHCP Start/End" in the OpenVPN server setting.

                        Any idea?

                          Yes.
                          A DHCP server needs a host address. Not a network address, like the one terminating with 0.

                          But maybe this is just don't care situation because :

                              Me neither ;)
                              But a firewall does what you want - you are the boss ^^
                              Idea : make your rules verbose and have a look at the firewall logs.
