For the first time I had succeded in setting my cable modem (Netgear CG300) up to Port Forwarding the 3 ports NR2003 needs to be able to host multiplayer races.

You don´t have to do this just to become a client. Only if you want to host.

The history was that I had introduced a friend in the same building that I live to the fabulous NR2003 GTP mod.
We connected first our computers via a 50m long cable out of our windows in a kind of LAN connection.
And we could both be client or host without any port forwarding.
So long so good.

Then we decided instead to use the pretty good internet facilities in NR2003.
Ie use our internet connections instead of the cumbersome 50m cable-window connection.
Great dissapointment. None of us could host. Timeout everytime we tried to start a multiplayer race.
Fu*ng ::crap::. How do others manages this problem?

And it seems like nobody round the net actually tries to help others with this multiplayer setup problem.
The only "help" to get is that a lot of smartguys stupidly repeat the advices from the "NR2003 ReadMe.doc"
http://simnascar.wor...e-documentation
But for most normal people this documentation wount help them. It is pretty un-understandable.
And if you use your critical glasses against these smartguys it looks like they dont understand it either:-)

So here is a more down to earth explanation of how to port forward in a cable modem/router.
First you have to get your PCs local IP address the socalled Eternet adapters IPv4 address.
No sweat.
Just open a commandline in Windows and enter (ipconfig).
The following message appears (hopefully:-)

Ethernet adapter Local Area Connection:
   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : kgjhkjgkghkgkhgk
   IPv4 Address. . . . . . . . . . . : 191.169.10.5

OK. Write the IPv4 Address down on a paper.
Thats all we need because the only other thing we have to use is the NR2003s 3 port numbers (32766, 32767, 32768) or simplified port(32766-32768).

Now you have to "get into" the modem via your PC and browser.
For the CG3000 you simply do this by typing (http://192.168.0.1) in the address field of your Internet browser.
A login window appears which displays a demand for a UserName and Password.
The default values for this is in the CG3000 UserName(admin) and Password(password).
For other router models use the net to find default UserName and Password.

But on the CG3000 now opens a status window with some info we dont have a use for now.
So therefore we simply use the menu to go down to (you have probably guessed it) Port Forwarding.
Its so simple that you can have a laugh.
In the Port Forwarding menu there is a line called Add Custom Rules with some emty fields just waiting for our input.

FIELDS:
Name(GTP)
Start port (32766)
End port(32768)
Protocol(Both)
Local Ip Address (191.169.10.5)

Then you just have to select: Add
and then choose: Logout

Now your modem/router setup for Port Forwardig for NR2003/GTP.
Piece of cake, right?
