addon gwar3000 port forwarding

[grolma]

im trying to set this up for a friend. It is IMHO one of the most incomprehensible interfaces/manuals Ive come across and the UK support phone line have no idea.
I want to forward a port on the modem/router to an internal dekstop.
Ive activated VNC on the the portforwarding/rules/apps menu and from my remote linux box can now

# telnet xx.xx.xx.201 5900
Trying xx.xx.xx.201...
Connected to xx.x.x.201.
Escape character is '^]'.
RFB 003.003

in the portforwarding/custom rules menu
what is the source IP address ext LAN one ? modem/router one ?
destination IP address is ( I assume ) 192.168.1.2
destination ports will be 5900 5900
Whats the destination port map mapping what to what ?

FFS all I want to do is
forward a 5900 on the firewall to 192.168.1.2:0



I want to forward this to 192.168.1.2:0 (windows machine)

Welcome :)

You should have 4 settings
Start Port - 5900
End Port - 5900
Protocol - Both (UDP & TCP)
IP - 2 (192.168.1.2)

thanks - the manual/techh help really are awful. The problem is that it doesnt make clear what the various bits actualy mean .
Destination IP is where I want to go to (192.168.1.2)
destination IP netmask
anything other than 255.255.255.255 ?
Source IP =
IP of the router?
IP of my external NIC ?
+ netmask - ?to allow me configure LAN based access?

hmmmm . Im goign to experimant a bit and report back .
