      Cheers for your answer!
      I configured NAT from LAN to Any for port HTTPS and had pfSense automatically create the corresponding firewall rule. Port forwarding, as I understand it, forwards traffic to a certain port from WAN to LAN. I'm not doing that for HTTPS.

      Here's the screenshot for my LAN NAT config:

      Did I configure my source NAT wrongly?

        Why would you do that?? There is ZERO reason to do that - delete ALL of those

        This is the specific rule that would be doing what your seeing. You have zero reason to do any port forwards like that.. Your sending all your traffic to pfsense wan.. Nothing would work!

        For stuff to get to the internet - outbound nat is what is used, and it would auto be setup.. You shouldn't have to touch it.

          I think I created the source NAT-ing in the wrong place. I did it on NAT/Port Forward, but shouldn't it be on the Outgoing tab?

            No port forwarding is where you would do port fowarding (redirection) - but none of those make any sense

            Out of the box pfsense would nat your lan traffic to the internet to wan IP. Via outbound nat

              so it seems we are posting over each other and now I'm a bit confused: to be able to go from LAN to the internet, should I use the Port Forward tab or the Outgoing tab?
              If it is the Outgoing tab, should that be automatically configured? This is what I have now:

              cheers!

                @bcnx said in Certificate problems with HTTPS traffic:

                to be able to go from LAN to the internet, should I use the Port Forward tab

                No - those nats would be done on the outbound tab - but you shouldn't have to touch it. Out of the box auto would nat anything from lan to your wan IP.

                delete all those port forwards you setup.. Other than those ssh ones you might want - those forward traffic from internet to your stuff on 192.168.x.100

                what are you trying to source nat? That is not a common thing to do - and only really needed to circumvent a local devices firewall, that doesn't allow access from other IP ranges other than its local network. Or to talk to a device that has no gateway setup.

                Traffic to the internet from your lan to the internet will be auto "source" natted to look like it came from your public wan IP out of the box with the auto outbound nat rules.

                  So I deleted the port forwarding rules and host in the LAN are working fine now. Those from my DMZ network still don't but I suppose no automatic outbound NAT configs were created? And so I need to create those manually?

                    @bcnx sure looks like they were I see 192.168.253 and 192.168.254 listed there. Did you put any rules on your dmz interface to allow traffic?

                    Out of the box lan would have an any any rule - but new interfaces would have no rules..

                    Pfsense will auto create outbound nat for any interface you bring up - but rules would not be there until you create them.. Only the lan interface gets the default any any rule to start with.

                      Thanks to your advice I was able to get things working, thanks a lot for that!

                      I'm familiar with Sophos and Fortigate firewalls, but this one has its particularities, but I'm happy to learn about them.

                      Cheers,
