ok so simply you must have static ip on your computer.
step 1:
click the two computer down at the bottom of your task bar and go to settings.(for vista it is network sharing center)-- forgot xp settings
If vista(view status)--- if xp just click properties
--- skip if xp.... a) if you clicked status clicked properties
Step 2. Once you clicked properties then click TCP v4 or TCP and go to that properties. after doing this, choose an IP within your router range. For ex. 192.168.0.2 - 192.168.0.255
-- Once you have ur computer set make sure you put in Default Gateway and Mask.
-- Also if you kno the DNS that your network gives you to connect to its best if you use them and plug them in your router as well, or if you dont, then just obtain dns from router.
Step 3: Once you have your computer configured, you must configure your ports on your router to the ip that you put in TCP settings. so i forgot the ports on kal but i think it is 30001,40001, and 50001 so you must have 3 different port settings specific to kal. also one for mssql which is 1433 and 1434 depending on what you want. if you run a websire port 80 as well as ftp 21
so you must forward atleast 5 or 6 directly to your computer if you run all these on your computer. After doing this, you must configure the ip in your client.
If your running from an outside computer(off of your netweork, its whatever your router says it is, however i would try in investing in a domain or one that automatically updates when your ip updates.)
If your running inside your network and not on the same computer, you must put it to the ip as 192.168.0.X
X = the computer with the server.
if running on local computer then it will be 127.0.0.1 or localcomputer
