        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.

                    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 ^^
