          PC at LAN A: 10.8.0.3 connected. Pfsense at LAN A: 10.8.0.2 connected.
          PC at LAN B: 10.8.0.4 connected, PC at LAN B: 10.8.0.5 connected, Pfsense at LAN B:  connected

          This is quite confusing.
          What are you trying to achieve?

          Can you draw a diagramm of your networks and which ip range you have where?
          Also can you post screenshots of your config from the client and from the server?

          We do what we must, because we can.

            Hi, This is the network..

            I hope to integrate OpenVPN to make tunnel for LAN A and LAN B so there can share files, play games together.

            PFSense Box 1 Configuration:
            Protocol: UDP
            Dynamic IP (Thick)
            Local Port:1194
            Address Pool: 10.8.0.0/24
            Remote Network: 192.168.1.1/24
            Client to Client VPN: (Thick)
            Authenication method: PKI
            CA: INserted
            Server CA: INserted
            Server Key: INserted
            DH: Inserted
            DHCP-OPT: DNS Domain Name: (Use domain which i host at dyndns.com)
            DHCP-OPT: DNS Server: 202.188.0.133 (DNS Server ISP)
            custom option:
            ;local 60.xx.xxx.xxx
            ;dev tap
            ;duplicate-cn
            ;comp-Izo
            ;max-clients 150
            ;persist-tun
            ;push "dhcp-option DNS 202.188.0.133"
            ;push "dhcp-option DNS 202.188.1.5"

            –----------
            PFSense Box 2 (Client)
            Configuration
            Protocol: UDP
            Server address: 60.xx.xxx.xxx
            Server port:1194
            Interface IP:192.168.1.1/24
            Proxy port:3128
            Cryptography:BF-CBC(128Bit)
            Authentication method:PKI
            CA certificate: Inserted
            Client certificate: Inserted
            Client key: Inserted
            Custom options:
            ;dev tap;persist-key;persist-tun;ns-cert-type server;comp-lzo;remote 60.xx.xxx.xxx 1194

            Result
            Both PFSense show  Initialization Sequence Completed

            But i cannot ping in PC 1, PC2 nor PC3 to each other

            So, I install Window OpenVPN GUI
            and configure the file:
            –----------

            Client at Window XP Config log files:
            client
            dev tap
            proto udp
            remote 60.xx.xxx.xxx
            resolv-retry infinite
            nobind
            persist-key
            persist-tun
            ca ca.crt
            cert client1.crt
            key client1.key
            ns-cert-type server
            comp-lzo
            verb 3

            Result:
            Client success connected BUT if both side more than 1 PC connect then cannot get link together...

            It is i use wrong method on construct the network or insert wrong code??

            Thanks

              I suggest you start reading on http://openvpn.net/howto

              I see that you only want to connect two LAN's together.
              For this dont use a PKI but use a shared key setup.
              –> resetup your openVPN connection.

              The custom options you added are mostly useless since they are generated by pfSense per default or ther eis a checkbox to enable them

              For your test with a windows XP client... you cannot connect multiple clients with the same certificate.

              We do what we must, because we can.

                      This is the server share key conf

                      Note: 192.168.10.0/24 is server site
                      192.168.1.0/24 is client site
                      192.168.100.0/24 is vpn tunnel subnet ….

                        We where able to solve the problem per MSN.
                        yce_kelvin forgot to mention that the server had more than one WAN.

                        http://forum.pfsense.org/index.php/topic,7001.0.html

                        The rule on the LAN had as gateway a loadbalancing-pool.
                        The problem was solved through adding another rule with as destination 192.168.1.0/24 (subnet on the client side) and gateway * above the rule with as gateway Loadbalancer. (see screenshot posted by yce_kelvin below)

                              Site to site connection with share key is okay but cannot bridging.
                              Try to do another site-to-site bridging. If some one have experience before kindly share ur exp here. Anyone success before?

                                  Nobody will ever be able to use UDP broadcast based LAN games in a routed scenario.

                                  You NEED a bridge, or else a UDP proxy like this one: http://www.vttoth.com/tunnel.htm

                                  In about 3 weeks or so i will have a bit more time. If i'm not too busy with other projects i think i'll try to get this running since i'm interrested in this too.

                                    Bridge mode can successful for 2 LAN sites in a "normal" condition. "Normal" mean a normal office or group network. If those client is "cloned" then will meet the problem with MAC address issue. This is because if the PCs are cloned, that mean the MAC address also will duplicated.

                                    Bridge mode i use is form a pfsense as openvpn server and other client pc install openvpn with tap-adaptor. Client can be successful connected but need a different MAC address of TAP-adaptor. I m try to come out a script that can make the TAP-adaptor MAC address can change according to IP address.

                                    But, what i hope that is 2 site PF sense can form bridge mode and no need to do any setting or installation to the client PC.. It is possible.

                                    I know that PFsense routed VPN is not work with what i want.. Anyway i hope that i can make a successful case under GruensFroeschli help :)

                                    or someone interest on it can study together. My network knowledge is level 1 only ^^

                                    IT Computer System - I love it. Hope that every day is a happy day and the world is peace and green environment always.
