      @MaxHeadroom:

      Try to lower the ipsec Advance Setting

      "Enable MSS clamping on VPN traffic"

      Yes! It's work!
      Enabling this option without any parametr solved my problem
      Thanks!

      I tried leaving it by the default settings and it did not solve my problem. Here's another weird thing, I have a synology NAS which I manage through its web interface at https://ipaddress:35909. I can access that from across the IPsec tunnel, but not plain Jane https. My remote site is using pfsense and on the LAN interface (where I am doing all the testing from). My rules allow the LAN to access anything and everything.

      Anybody know what might be my problem?

      Thanks!

        Hi teladero

        Why not lowering the MSS ? what is your problem with the webgui ? Maybe the NAS Gui allow only acces from LAN

        If you want access the NAS over internet behind a pfsense  you have to  add a Firewall: NAT: Port Forward for the
        Nas

        Please be more clear with your request.

            What should I lower it to?

            I have had a site to site VPN up before with two Meraki security appliance. It worked beautifully.

            I do not want my NAS to be accessible through port forwarding. Sorry I wasn't more clear.

              I noticed that the default size was 1400, so I tried 1300 and that did not work. Should I just go smaller? If so, am I slowing my connection to the remote network?

              Thanks for all your help.

                No connection is not faster  ;D

                  The NAS (or any other device on my remote network) is not blocking http or https traffic. It used to work fine when I was on a meraki site-to-site vpn. Nothing has changed here except going to pfsense at one location. I can ping, do samba shares, remote desktop, etc across the vpn, so I know it is established. I can try and add some rules on the pfsense box to allow http traffic explicitly over the vpn. I will post the results.

                    I can't believe it…I added a rule to allow any traffic to the remote network, and it worked! The most bizarre thing is that you can clearly see the  two rules below it, allowing IPv4 and IPv6 traffic sourced from the LAN to anywhere. No clue why this was necessary, but hopefully it will help someone else in my position.

                    Thanks again MaxHeadroom!

                      That makes zero sense. What are the advanced characteristics on that second rule?

                      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

                        Makes zero sense to me as well. Here's what I have for advanced settings.

                          OK just limiters.

                          I would disable the rule you added, turn logging on on the main pass rule, try to open connections across the VPN, and see what they logs say.

                          Hmm. Limiters. I don't see anything that should do it but you might be hitting the 2.2.X limiter bug. Also disable the rule you added and try it without the limiters set.
