      Hi I have two pfSense on either side of the tunnel both running version 2.4.4

      I am able to bring up my tunnel but no traffic is passing.

      On both sides I have an IPsec rule allowing any any for the firewall.

      Here are my configs.

      Can anyone let me know what I may have missed?

        I recently had a similar problem. I could ping across the tunnel, but most other traffic would fail after upgrading to 2.4.4. Disabling Asynchronous Cryptography in VPN > IPsec > Advanced seems to have corrected the problem for me. As far as I know, this setting is not available in older versions.

          Thanks for the info.

          I just checked on both systems and this option was already disabled.

          Should I maybe enable it?

          Interestingly though:

          • pfSense A is having trouble with pfSense B's site to site tunnel
          • pfSense B is however able to establish 4 other siste to site tunnels successfully and communicate. THis 5th tunnel to pfSense A just refuses to work.
