      I assume that means you can't connect between 2 sites. If so, then you have to check routing, firewall rules and perhaps NAT.

            First off, you have to decide whether you're using IPSec or OpenVPN VPN. You will have to allow whichever you use through the firewall.
            Are you setting up a site to site VPN? Or "road warrior" VPN?
            You will have to ensure appropriate routing.
            Will the VPN terminate on the firewall or behind it? This will affect routing.

            So, sit down with a sheet of clean paper and sketch out what you want to do. Then you will be able to tackle the various issues in a coherent manner. Include port numbers on the sketch. For example the default for OpenVPN is UDP port 1149. Also include target addresses on the sketch, so you'll know how to configure routing. I also see you're using VLANs. Include those in the sketch.

            Also, while I have worked with IPSec VPNs, I've only set up OpenVPN on pfsense.

              So you are trying to connect the 192.168.20.X subnet to the 192.168.30.X subnet?

              And have a common subnet of 192.168.10.X between the firewalls?

              Something like?

              {Subnet1 .20}---[pfSense]==={common WAN .10}===[ASA]---{Subnet2 .30}

              What is not working?

              How is your IPSec configured in pfSense?

              Do you see errors in the logs?

                      Sounds like a missing firewall rule at the ASA then.

                      Or you may be pinging from the wrong source in that direction. If you ping from pfSense directly be sure to select the LAN as the source.

                          Those don't help at all.

                          It's either a rule missing in the ASA.

                          Or you are pinging incorrectly without choosing LAN as source.

                          Post a screenshot of the ping failing.

                              OK great. So that ping should match the ipsec policy and be carried.
                              If you run a packet capture on the ipsec interface you would see the requests leave.

                              It looks like you are missing a rule on the other side to pass it.

                                  It could also be the host at 192.168.30.1 rejecting it.

                                  You should use a non-default password on the ASA. 😉

                                      Ok, why is it configured as mobile IPSec? That's a site-to-site tunnel.

                                      In that screenshot it is up at phase1 only. You need phase2 to be up to carry any traffic.
                                      But you said you could ping from the ASA to pfSense so it must have been up then.

                                      What exactly are you showing us there?

                                          Ok, well it's not connected at phase 2 so check the IPSec logs for errors.

                                          How is it configured? What are you connecting to it with?

                                          Did you follow a guide for this?
