      Hello everyone, I need to configure pfsense so that I can access from the lan to a service on the lan via wan. I know it is twisted but in this way I would have only one link to give to the customer to access the service

      currently I managed to configure from captive to lan via wan, but reporting the same configuration on the lan does not work.

      Thanks!

          I tried to create a NAT with this configuration but it doesn't work:
          Lan is 192.168.3.0/24

          Interface: LAN
          Source: any
          Source port: any

          Destination: WAN Address
          Dest port: 9080
          redirect ip: 192.168.3.200
          redirect ip: 9080

                  Better use Split DNS...

                    yes you are right, but if it's only one port it's not a big deal, personally i use bind with split view for that but the configuration is somewhat less easy

                        i don't see anything wrong here
                        i can only give you some point to check as i don't know why it's not working for you
                        do you have a corresponding Firewall Rules under the WAN interface?
                        overlapping NAT rules maybe?
                        wrong firewall rules order?
                        does LAN have a rule that permit to go out using port 9080 ?
                        you didn't mentioned what kind of service is it but is your service tcp only ?
                        anything under firewall log ?
                        does it work if you try from the internet or are you only trying from the lan side?

                        if nothing work maybe try Method 2: Split DNS

                          The url you give to some client has zero to do with if you do nat reflection or not.

                          The correct solution when your local to the service that is behind a nat firewall is to resolve whatever that fqdn is to the local IP and not the public one.

                            uhm he didn't mentioned url but link, if he is trying with url instead of ip than yes you are right, you can't do that with nat reflection but only with split dns

                              url or link - same thing.. What do you think a link is?

                              If he is giving the client an IP - he is doing it freaking WRONG!!! Period!

                                    Give your client a public fqdn vs an IP... That way if it ever has to change you do not contact all your clients (even if only 1) and say hey that link is now http://y.y.y.y vs http://x.x.x.x

                                            Average lets call it 10$ for you domain name a YEAR... there is one thing if this your buddy and you want him to access your ftp server so you can exchange anime or something.. But this is a client - how are you doing any sort of business at all and not have a domain to use?

                                            Ok i know this, actually i manage over 50 domains for various customer, and obviously give them a domain to do this is the most correct solutions, but my question is why if i try to access to the service running on lan through public ip from the captive network it works, but if i try lan service through public ip from lan it doesn't work.

                                            Currently the customers would not understand why it would have to buy a domain to use something he can use normally from the guest network
