      On the site 2 pfSense you have to allow the access on LAN, since this is the interface which the packets come into the box. By default on LAN pfSense has a default to any rule already. So if you haven't deleted or restricted this rule, there is nothing to do.
      On site 1 the packets come in on the OpenVPN interface, so on this box you have to set a rule on OpenVPN to allow the access.

      The routes are to be set in the OpenVPN settings by adding the remote network you want to reach to the "Remote Network/s".
      On site 2 in the "IPv4 Remote Network/s" box you may have 192.168.3.0/24 (site 1 LAN) for now. Here you have to add the VLAN60 subnet. So for instance if VLAN60 is 192.168.60.0/24 you have to add the subnet this way:

      192.168.3.0/24,192.168.60.0/24

      On site 1 you have to put the LAN subnet of site 2 into the "IPv4 Remote Network/s", if it isn't already.

        Thanks for the reply @viragomann, so i added what you said on site 2 the VLAN but cannot ping from pfSense site 2 to the LAN see picture

        So this is my Site2 my LAN on site 1 is 192.168.3.0/22 and my VLAN which i need to ping is 192.168.60.0/24
        Screenshot from 2019-11-26 22-46-08.png

        And this is my Site 1 as my site 2 LAN is 192.168.15.0/24
        Screenshot from 2019-11-26 23-19-18.png

        Not sure what i missed?

        Thank you

          @killmasta93 said in Site to site ping with VLAN?:

          my LAN on site 1 is 192.168.3.0/22

          ? Should be 192.168.0.0/22!
          Maybe that confuses some clients.

          Try a ping from pfSense 2 to the LAN IP of pfSense 1. Try also a ping to the VLAN60 IP. If these pings work, change the source address to LAN and try again.
          If all pings do fine try to ping devices behind pfSense 1.

            As @viragomann alluded to, if site 1's LAN interface is configured with 192.168.3.254/22, then site 2's config should have 192.168.0.0/22 in the IPv4 Remote network(s) section.

            I haven't seen anything overly complicated here. What you're trying to accomplish is fairly straight forward. We need to get the traffic routed over the tunnel and then allowed through the firewall at both ends.

            I'd suggest a few things until you establish basic IP communication:

            • Post your server1.conf and client1.conf (both located here -> /var/etc/openvpn)

            • Turn off the software firewall on the endpoints you're testing with.

            • On site 1, verify there's a LAN net/any rule on the LAN tab

            • On site 1, add an any/any rule to the VLAN60 tab

            • On site 2, in the OpenVPN client config, modify the IPv4 Remote network(s) section so it reads "192.168.0.0/22, 192.168.60.0/24"

            • On site 2, verify there's a LAN net/any rule on the LAN tab

            • Add an any/any rule on the OpenVPN tab on both ends

            • Verify all devices are using PFsense as the default gateway and have the correct subnet mask configured.

            • On site 1, verify VLAN60 is configured with the network and mask you're expecting it to have. If you find a discrepancy, modify the IPv4 Remote network(s) section on site 2's config.

              @viragomann thank you for the reply, so i changed on the part which i made a mistake to 192.168.0.0/22
              so from pfsense 2 i ping pfsense 1 LAN which is 192.168.3.254 which works

              PING 192.168.3.254 (192.168.3.254): 56 data bytes

              but not to IP 192.168.60.100

              The part of change the source address to LAN? not sure what you mean on firewall rules on pfSense 1?

                  Configs look good, so once packets from site 2 hit the firewall that are destined for 192.168.60.0/24, they should get routed to site 1. Conversely, once packets from site 1 hit the firewall that are destined for 192.168.15.0/24, they should get routed to site 2.

                  At this point, it's all going to be troubleshooting, I would run a traceroute on both ends, see where the packets stop and troubleshoot from that point. Something is interrupting (or blocking) packet delivery, so every point along the data path will need to be traced and examined. Start checking routing tables, conflicting static routes, firewall logs, and re-examining firewall rules. I would also verify that there are no persistent routes on the endpoints you're testing with.

                  A couple of things I see that should be looked at:

                  • On the LAN tab on site 2, that LAN net/192.168.60.0/24 is redundant (since there's a LAN net/any right below it), but since the rule is there... it does appear to give some insight. There do not appear to be any hits on that LAN net/192.168.60.0/24 rule, which suggests that traffic may not be making it to the firewall, so that will need to be looked at.
                  • I'm not sure what the TELEFONIAIP tab is (maybe VLAN 60?) but if it's something that you're trying to hit from site 2, there also appear to be no hits on the any/any rule, so it looks like traffic isn't making it there.

                  We also have no insight into the network design at each end, so if there are any downstream routers, L3 switches, dual WAN, isolated networks behind a 2nd firewall, etc... that will all have to be looked at.

                    @marvosa Thank you for the reply, so troubleshooting this still cannot ping the VLAN 60.

                    On the LAN tab on site 2, that LAN net/192.168.60.0/24 is redundant (since there's a LAN net/any right below it), but since the rule is there... it does appear to give some insight. There do not appear to be any hits on that LAN net/192.168.60.0/24 rule, which suggests that traffic may not be making it to the firewall, so that will need to be looked at.

                    i added the rule thinking it was needed but i guess its not needed

                    I'm not sure what the TELEFONIAIP tab is (maybe VLAN 60?) but if it's something that you're trying to hit from site 2, there also appear to be no hits on the any/any rule, so it looks like traffic isn't making it there.

                    correct that is the VLAN60 but howcome no traffic even if i put on the VPN to be able to see it?

                    as for the traceroute
                    i ran from a server which has 192.168.15.253 on site and got this on the states of site 2 pfsense

                      As you can see from the traceroute, the traffic never makes it to the tunnel. The question is why. If there's no added complexity behind PFsense on either end, the first thing I would do is start checking routing tables on both endpoints and both PFsense boxes.

                      If you post the routing tables we may be able to help. Also, are either of your endpoints dual-homed?

                          • Site 1 shows 192.168.15.0/24 being routed towards 192.168.90.2 through the ovpns2 interface, which is site 2's end of the tunnel and is expected
                          • Site 2 shows 192.168.0.0/22 being routed towards 192.168.90.1 through the ovpnc1 interface, which is site 1's end of the tunnel and is expected
                          • However, Site 2 also shows 192.168.60.0/24 being routed towards 192.168.60.2 through the ovpns2 interface. <---Here's your issue... and it's the reason why traffic is never leaving site 2. Based on the site 2 config you posted, we should be seeing 192.168.60.0/24 being routed towards 192.168.90.1 on the ovpnc1 interface.

                          So, you have a conflict @ site 2 that is screwing up your routing. Per site 2's routing table, 192.168.60.0/24 is already being routed somewhere else in another server instance (ovpns2), which should correspond to server2.conf. You will have to find the server instance that's running at site 2 with the duplicate entry of 192.168.60.0/24 somewhere in the config and make adjustments accordingly.

                            Thanks for the reply, so the issue is on the site 2 pfsense?
                            so from what i understand that site 2 is routing the the network 192.168.60.0/24 in another server?
                            I checked on the site 2 pfSense box any rules that has that network but nothing. wouldn't that route be what i put on the site to site option to route?
                            My other question is why does it show ovpns2?

                            Thank you

                                  Correct, the issue is at site 2. It looks like you made adjustments to ovpns2, which is the first step, so now we need to get the correct route added for 192.168.60.0/24. Rebooting will work, but we can use that as the last resort cause we should be able to resolve this without a reboot. I would try bouncing the tunnel first in one of two ways:

                                  1. Status -> Services, then restart the service that is running the tunnel to site 1
                                  2. VPN -> OpenVPN -> Servers, then edit the server that is running the tunnel to site 1 and re-save it.

                                  After the tunnel is bounced, check the routing table on site 2... there should now be a route for 192.168.60.0/24 using 192.168.90.1 as the gateway on the ovpnc1 interface. If not, then go ahead and reboot site 2.

                                  Once you see the route mentioned above, you should now be able to communicate across the tunnel to VLAN 60.
