      Dude.. The CLIENT firewall… Why would that be in logs on pfsense?

      What OS is your client?

          So where did you state that?  What IP are you trying to ping?  An IP on the network in your site to site connection?  Or the pfsense client vpn IP, or its lan or its wan??  What?

          Did you create a peer to peer or a remote access on the server pfsense?  What networks do you have at each site??

          edit:  Dude while I don't normally mind PMs with questions, etc..  Post your stuff in this thread… And what networks are on each side and what is the tunnel network..  Who exactly are you trying to ping..  These are basic questions that we need to know if you want any sort of help..

            i can ping from client(140.254) to server(114.254) , but not from server(114.254) to client(140.254)

            any other info needed , sorry for giving less details

              please just post up a gui shot of your client config and server config..  Your not editing the .conf manually are you?

              What do you have in your outbound nat on the client?  On the server?  What is the routing table on pfsense of the client look like and on the server side..  On the client you should be putting in what networks are remote..

                  so your not natting anything through your vpn interfaces.. Fine since your just all local networks..  But you don't have anything in your remote or local networks  You don't normally have to push routes.. Unless your doing something specific odd..

                  Where are you routing tables from pfsense?

                          no that is not your routing table…  under diagnostics routes, it will list out your routing table.

                          Why should you have to put it in overrides if you would just setup the server and client correctly in the first place?  With the local and remote network fields.

                            SSL/TLS still needs an iroute via the CSC section for each client.

                            Much easier in 2.2.5 than it used to be, but that iroute is often a last Gotcha in S2S links.

                                Definitely necessary, in the current pfSense versions, you simply enter into the server screen a comma delimited list of all the subnet "LANs" on all the client OpenVPN's you want to reach.

                                Then in the Client Specific Overrides section you make an entry for each client and list the LAN subnets that client will use.

                                It seems a little convoluted for a single S2S connection, but it lets you setup a single server and easily connect many (I have a link that uses 20+) clients each with more than one subnet.

                                The only hitch is that the client subnets can't overlap -  takes a little planning, but welcome to networking  ;)

                                      Client export is only for Remote access type OpenVPN servers ("Roadwarriors").

                                      If you need both S2S and Remote access on the same pfSense box, I normally just create a second server instance listening on a different port and using different CA's and Server Certs.

                                      Personally I prefer to keep them separate anyway, easier to track who's logging in remotely.

                                        my requirement is
                                        one vpn server have multiple clients ==> so that users can have access all regions
                                        if i want to work from home i need vpn key
                                        so users from other network should connect this server using openvpn. so client export is necessary.

                                        so what type of vpn server i have to use S2S or remote access open vpn server .

                                          When you create an OpenVPN server you have to specify the "Server Mode":

                                          Peer to Peer (SSL/TLS)  - Used for pfSense to pfSense connections, two routers that are connected 24/7
                                          or
                                          Remote Access (SSL/TLS) - Used for mobile or sporadic devices, laptops, cell phones, users at home computers.  They connect when needed.

                                          As I said before, you create the type (or both) that you need for your situation.

                                          Perhaps it would be worthwhile to draw a simple diagram of your envisioned setup so we can all be clear as to what you're trying to accomplish.
