            In Firewall/NAT, I set NAT Reflection mode for port forwards: Enable (Pure NAT) and enable automatic outbound NAT for Reflection

              You didn't seem to link the nat to a firewall rule on the interface your wanting to nat from.. Are you testing it via nat reflection or from actual outside.  Your top forward has a link to firewall rule.

              Did you go through the troubleshooting doc - where are you failing?

                    are you inside your network hitting your public IP hoping to be reflected back in… Or are you testing from outside your network to your public IP?

                    That port does not match any of your forwards.. Your post shows port 3299 but your forwards are 3306

                        you telnet from where?

                        And what is wanvpnt?  Is that some vpn interface.. Are they forwarding inbound.. Go through the doc..  Validate that the traffic is even hitting pfsense to be able to forward..

                        It really should only take about 30 seconds to figure out what is wrong with a port forward.. Pfsense can not forward what it is not seeing is a very common issue..  Wrong port used, or server has its own firewall blocking the traffic, etc..

                        A 30 second sniff on your wan and then lan interface tells you if the traffic is being seen and forwarded to what you want to forward it to, etc.

                        canyouseeme.org is a handy site to validate a port is open from outside your network..

                          I am telnet from Internet
                          WANVNPT is interface WAN. I have two interfaces WAN, and running load balancing. And WANVNPT is not default
                          When I telnet from Internet, port is close in pfsense
                          Before i reboot pfsense, its action normal
                          After reboot, i can't NAT.

                            Port forwards are rdr rules and will come after that. Did you trim the output? If so you didn't show the rules you are asking about.

                            Your original image did not show port 3299. What specific port forward is not working?

                            Look at - really look at - all of these things:

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