      Look,

      closed one vpn between two pfSense 2.2.2, I can ping on my side B pfSense to other machines on the side A.

      The error is when the affiliate machines (side B) can not ping the machine side A.

      The rules are released. both at headquarters and in branch.
      Using OpenVPN client in a season I can without problems.

      Side A - 192.168.10.0/24
      Side B - 192.168.2.0/24

      
Side B - 192.168.2.0/24

              You should normally use "tun" mode and there will be (at least) 3 subnets with different addresses and routing between them:
              a) Local LAN
              b) Tunnel subnet
              c) Remote LAN

              As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."

                network 192.168.181.0/24 to change with the other vpn client, the problem still remains, only Configo dripping from the pfSense .. the machines to hand Failure. however the log is okay.

                  Why tcp?  Why are you doing things differently than every walkthrough and guide tells you to do?

                      There is not an obvious problem there. Post the OpenVPN server settings at the other end and also the firewall rules on LAN and OpenVPN at each end.
                      Try traceroute between clients at each end and see where it stops, or if it starts going out some WAN - that will give you a clue about where things go wrong.

                          At minimum, you should specify the Site B subnet in the Site A "IPv4 Remote Network/s" box.

                          You need to let the server know it will be routing traffic for 192.168.2.0/24 through the OpenVPN conx.

                          Post the Site B Client screen as well to make sure nothing else is missing.

                              As has been said, you have no remote networks specified at either end.  That's how pfSense knows what traffic to route over the tunnel.

                                  You need 192.168.2.0/24 in the remote networks on the server.  I believe you also need to put the 192.168.181.0/24 tunnel network in the client side.

                                      Are you certain the remote hosts will respond to pings from foreign networks?  This is often the firewalls on the destination hosts.  What version are you using?  There have been few problems with OpenVPN on 2.2, 2.2.1, and 2.2.2.  No reason to change versions.  All you have to do is configure it correctly.

                                            I have plenty of OpenVPN site-to-site links on 2.2.2 and they work fine just like they did in 2.1.5 - put the right subnets in Tunel, Local and Remote Network/s boxes on server and client, make sure the firewall rules on LAN and OpenVPN at both ends allow the relevant traffic - that is all there is to it.
                                            When I setup a new office it takes only a couple of minutes to bring up OpenVPN site-to-site links back to our main offices, it really does work.

                                            As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."
