        please draw a map for us to understand your network topology. your pfsense only has 1 interface - a LAN interface ?

            wan 192.168.5.1 subnet 255.255.255.0

            The way you have written this, it just won't work. It is not possible to have the same subnet on LAN and WAN. So there is some problem with us being able to understand what you mean.
            What is connected to the WAN NIC of pfSense?
            What is connected to the LAN NIC of pfSense?
            Please try and draw a network diagram of what hardware is connected where.

              adsl_router(192.168.5.1-255.255.255.0) –------- pfsense (192.168.5.2-255.255.255.0) <<< 15 LAN PC (192.168.5.XX 255.255.255.0)
                                                                                                                        |
                                                                                                                        |
                                                                                                            remote pc 10.0.6.6

              this is what i want.

              that 15 pc and pfsense working properly no any problem.
              i want to remote pc add to that lan
              installed openvpn client to win7 pc. and connected to pfsense. pinging 192.168.5.2 is OK. web access and internet ok too.
              only problem is i can't ping or any access to that 15 pc
              firewall rules automaticly created. and i tried to push route 10.0.1.0 255.255.255.0 too

                If you want to solve this problem. Firstly you must change modem network subnet. Because your modem and pfSense box are same network. Modem and local network shouldn't be same subnet. They must be different subnet. That's not pfSense problem. It is routing protocol rules. And go to modem gui change modem ip address and pfSense Wan ip address and wan gateway address. You will see problem solved.

                    I have no idea why your clients worked on LAN when you had 192.168.5.* addresses on pfSense WAN and LAN. Maybe you have pfSense in transparent bridge mode?
                    Anyway, now you have different subnets on LAN and WAN, which is good. Hopefully the LAN clients in 192.168.7.* are working fine and can get to the internet.
                    In your OpenVPN server, put "192.168.7.0/24" in "Local Network/s". Then the OpenVPN client should be given a route to 192.168.7.0/24
                    Make sure your OpenVPN tab has a rule that passes traffic to destination 192.168.7.0/24 (or pass destination all).

                        the lan pc's on the 192.168.7.x range have pfsense set as their default gateway ?

                        could you attempt todo the following in windows command prompt:

                        from VPN: tracert -d 192.168.7.X
                        from LANPC (when vpn is connected): tracert -d 10.0.6.6
                        also some diagnostics–>packet captures would be helpfull (try pinging from both ends while it is running)

                          hi heper.

                          thats outputs

                          C:\Users\Live>tracert -d 192.168.7.5

                          En çok 30 atlamanın üstünde 192.168.7.5'e giden yolu izlemek

                            That is very strange. It is routing from the OpenVPN client across the VPN link to pfSense, but then pfSense is sending it out the WAN 192.168.5.1 to the public internet. I can't think how that could happen, because 192.168.7.5 is on the local LAN of pfSense, so it has to be delivered directly there.
                            What is in Diagnostics->Routes IPv4 section on pfSense?

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

                                  Hi Everyone,

                                  Firstly @aykiri1

                                  I confused. Because there was one network when you started this topic. And then there are many networks (192.168.4.0/24, 192.168.5.0/24, 192.168.6.0/24, 192.168.7.0/24 and your tunnel networks).

                                  what are your adsl modem ip and your pfSense wan and Lan ip address? You told us that adsl modem ip changed 192.168.6.1 and you pfSense LAn ip address 192.168.7.2

                                  @aykiri1:

                                  hi phil

                                    hi SGTR

                                    my second lan and second wan interfaces not important becasue i want to access only lan1 (LAN)

                                    ofcourse i made  changes when get info from someone then test by test.

                                    (wan=192.168.6.2    wangw=192.168.6.1)
                                    modem ip 192.168.6.1–-------------------------pfsense (lan 192.168.7.2)------------------------------ clients 192.168.7.xx
                                                                                                                          |
                                                                                                                          |
                                                                                                                openvpn client 10.0.6.6

                                    firewall rule  opnvpn any to any and any port pass added
                                    openv vpn client connecing to server get ip 10.0.6.6 web access pfsense OK. internet OK. lan access NOK

                                    thx

                                      persist-tun
                                      persist-key
                                      cipher AES-128-CBC

                                        pfsense sets the interface ip in the client-config … in your case this is probably 192.168.....

                                          i fixed it. i changed lan and lan2  ip's  1 to 2    2 to 1 then access now. i think problem is push route. not sure.
                                          thanks all.

                                          some pc's not pinging from vpnclient. and firewall disabled. must i make any ?

                                            if "some" pc's are not working and others in the same subnet are working, then the ones that don't work, probably have a wrong gateway set in their config or have a local firewall
