      @johnpoz Sorry for the late reply. I'll try to disable my tunnel tomorrow and let you know the outcome.

          @johnpoz Actually, that's not true. When I trace the ping, only the tunnel IP goes through the tunnel. Everything else showing the local system ip with the message unreachable.

            @sutha dude turn off your vpn client on this box and your issues will go away!!

            A vpn client will route traffic not set to the local network out the vpn.. So yeah trying to go to 192.168.60 vs 192.168.50 will go your vpn client tunnel... Pfsense can not route traffic its never seeing.. Ie your sniff on your lan not showing any traffic when trying to go to 192.168.60 because its being routed out your tunnel

              @johnpoz Does this mean I'm unable to create another interface for my local system as I was planning now?

              My scenario:

              A tunnel exists: site-to-site VPN connection.

              I'd like to have another area for locally separated traffic. I don't want, as I mentioned earlier, Area 2 to communicate with Area 1, but I have users in Area 1 who need to access Area 2.

              Do you think this is possible?

                @sutha if you want a site to site tunnel - create that on pfsense..

                Yes you can filter traffic that pfsense routes.. If you want client X to be able to get to vlan Y, you can allow that, if you want client A not to go to vlan Y from vlan X you can block them..

                  @johnpoz Yes, that's what I'm looking for. Currently, I have disabled two of the rules, and after reboot, my system suddenly went offline. I need to go to my office to see what happened. Once I have my system back online, I can provide you with some more details.

                    @sutha So, now I have removed all the rules and disabled the tunnel as well. I've also removed the lan1 and lan2 rules. Currently, I have no internet access and no connectivity to any system. Since I have no internet, I enabled an 'any' rule on lan1, and now I can see there is internet access for lan1 PCs. However, I still have no internet access on lan2. Therefore, I repeated the same steps I took for lan1 on lan2, and now I have internet access on both interfaces.

                    I'm now able to ping from 192.168.50.100 to 192.168.50.1, and when I enter this IP:192.168.50.1 in my browser, it took me to the pfSense web configurator. However, when I attempted to ping a pc on lan2, it failed. I moved to over to lan2 pc and did the ping to an ip 192.168.60.1 and it was successful. Furthermore, I tried to access the pfSense web configurator from lan2 using the IP 192.168.60.1, and it successfully redirected me to the web configurator.

                    At this point, I don't have any rules other than these two. Anyone got any idea what is blocking here, I have disabled my windows own firewall tatally on both system.

                      @sutha Realistically there’s only a handful of things it can be:

                      • Incorrect subnet mask on pfSense or PC
                      • Incorrect gateway on either PC
                      • firewall on either PC
                      • firewall rule on pfSense

                      If it was a VLAN, VLAN/switch config.

                        It's almost certainly not a gateway problem since hosts on both LANs can reach the internet.

                        It could be a subnet mask problem if hosts are configured statically. If they use DHCP it probably isn't since you cannot configure conflicting subnets in pfSense.

                        If any hosts still have two NICs or additional IPs in both subnet they will be unable to connect to the other subnet.

                        Try to ping 192.168.60.1 (the pfSense interface address) from a host in the 192.168.50.X subnet. If that works then routing and firewall rules are fine and it's almost certainly the hosts themselves blocking the traffic.

                          @stephenw10 I was talking in general and wasn’t clear. Low on coffee. :)

                            Now do the sniff.. When you ping a 60.x IP from a 50.x device.. Do you see the traffic get to pfsense?

                            And like to see the output of ipconfig /all from a device.. This will validate your mask is no messed up. And for good measure output of route print..

                                @stephenw10 I'm able to ping from lan1 IP:192.168.50.100 to lan2 ip: 192.168.60.1 and from lan2 ip: 192.168.60.50 to lan1 ip:192.168.50.1.
                                Works fine, but I'm unable to ping any other local pc. Example:
                                from 192.168.50.100 to 192.168.60.50, not working.
                                from 192.168.60.50 to 192.168.50.100, not working as well.

                                  @sutha And you could have 14 other interfaces.. On this machine and 3 different vpn interfaces.. How about a simple ipconfig /all output and a route print..

                                  $ ipconfig /all

                                  How about the 30 seconds it takes to do a packet capture? To validate traffic is actually going to pfsense and not some vpn tunnel you have that failed to mention..

                                    @sutha said in Unable to connect between lan1 and lan2:

                                    Works fine, but I'm unable to ping any other local pc. Example:

                                    If you can ping pfsense 192.168.60.1 from your 50.x device but not some other 60.x this SCREAMS!!!! firewall on the 60.x device..

                                    Again simple packet captures that take all of 30 seconds will finally prove to you its your device and not pfsense..

                                      Yup that^. Almost certainly a local firewall on the device you're trying to ping blocking it.

                                            @johnpoz All I can see in the packet capture, when Isent a ping to 192.168.50.1 or 192.168.60.1.
                                            I get a reply from the destination, but when I ping a local pc: 192.168.50.100 or 192.168.60.50.
                                            I get no reply from other side.
