with wan IP in server configurations the client gives this error:

I already foward the ports of my router and the certification is with wan IP as well. I didn't want to use hamachi. Besides changing the ip in the media pack of the client do I need to change anything?
UPDATE: The error was ½ÇÅ©·Îµå°¡ ÀÌ¹Ì ½ÇÇà Áß ÀÔ´Ï´Ù, I used the vsro address finder patcher tool and I got it to work. If anyone is getting the same error they should try that tool.
