        Based on the information given the only idea anyone can have is, "I guess it doesn't work."

        Look at Status > System Logs, IPsec for the times when the remote tries to initiate the connection. Anything interesting there?

          Hello,

          We are trying to setup a site to site ipsec vpn from PFSense to a Cisco RV042G Gigabit Dual WAN VPN Router. We have set it up on both sides. On Status > IPSec it says established but never seems to be established more then 5 minutes.

          As I was searching through the log this is what I keep seeing a lot.

Feb 6 10:05:27	charon		10[CFG] vici client 120 connected

          Also the error we are getting on the Cisco side is that it says "Waiting for Connection"

            This log shows that you went through the webgui to the status/ipsec page. Perhaps there is still data with the cause of the connection failure

                I understand correctly that the connection is established and the traffic goes through the tunnel ? And after 5 minutes, the connection drops ?
                Can I see the Cisco log ?
                And see the connection establishment log and the moment of the tunnel drop ?

                  The other side is trying to bring up a "Phase 2"

                  They are sending no encryption/hashing proposal (which is strange. I don't recall ever seeing that before.)

                  You side is set for AES-128-CBC, MD5, PFS Group 1.

                  There is no match and your side rejects the attempt.

                    OK matched the Encryption Algorithm and Hash algorithm and PFS key group again on both pfsesne and cisco and added Lan ip of Cisco to advanced config on pfsese to ping.

                    and it all now works, can ping from the firewall on both sides to local internal pcs.

                    but now need to figure out routing from local subnet of site A to local subnet of site B and vice versa
