      HI i want to enter from the WAN (from anywhere from the Internet) into my pc on lan behind pfsense box.

      xxxx.no-ip.biz:5800 (wan) –-> (lan) PC with VNC server x.x.x.x:5800

      I made port forwrd:

      If          Proto        Ext. port range  NAT IP  Int. port range  Description                                                                                                           
      WAN   TCP/UDP 5800                      192.168.2.3    5800
                                                            (ext.: any)

      and automatic firewall rulle enabled:

      Proto          Source  Port  Destination  Port  Gateway  Description
      TCP/UDP      *        *  192.168.2.3    5800  *

      Windows XP firewall added rulle for VNC server and his ports.

        The machine inside your LAN can get out to the internet and has the pfSense as gateway? Does the dyndns account actually resolve to the correct IP?

            Try setting the External address to 'Interface Address', instead of 'any'.
