This is my situation :
2 PC with Windows 2000 Professional, in a LAN. One have an ADSL connection shared. All (HTTP, ICQ, FTP, POP3) works well with WinProxy 1.5.
Now I want to run a Neverwinter Nights Dedicated Server on the PC not directly connected. For the information of the ports, see below. The technical support of Winproxy told me that "WinProxy cannot map UDP ports (only TCP ones)". Is there a software for me for all these things? (HTTP, ecc. + Dedicated Server) I'll divide the costs with some friends, so the price of the software is not a problem (1000$ IS a problem however... ;) ).
Info about the Neverwinter Dedicated Server :
1.03: How can I play through a Firewall? (Back to Top)
If you are trying to play through a firewall of some sort, here is some information for you to help you get connected. Neverwinter Nights uses UDP, not TCP for its connections. If you think that your firewall is preventing you from connecting to the game servers, please make sure that the following ports are open:
Ports 5120 through 5300
In addition to opening the ports listed above, you may need to allow incoming connections on the port you are running your server on (5121 by default) and forward those connections to the computer running the server.
If your server does not appear on the GameSpy game list:
Verify that it is does not appear for other users. It may not be appearing for you because your game is published by your external IP address, this address may not be valid from inside your firewall.
Verify that the server is accessible from the Internet, have a friend Direct Connect using your external IP address (ie not 127.0.0.1 or 192.168.*.*, these are local addresses).
If you are starting your module from the command line of the Windows or Linux dedicated server, try starting it from within the application.
If your module is very large or contains very large areas, try breaking it up into smaller pieces.
If you are wanting to make sure that your NAT is set up to allow the game to play here are some details.
Source port: 5120-5129
Destination port: 5121-5300
Source port: 5121-5300
Destination port: 5120-5129
On the Game Client side, here are some changes to make things go better. Go to your nwnplayer.ini file in your Neverwinter Nights install directory, and find the following section:
Our suggestion is to change XXXX to 5120.
