NAT and Dynamic DNS

Piplfox

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?

Yes PC use pfsence as gateway and has access to internet and updated public address is real pfsense wan address.

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