      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?

        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.

              Both server and client get same message,

              After connected, the server show the following log:

                  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 ….

                    Follow-up-note:
                    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 ^^
