Connecting to the external IP address!

Good evening. Please tell me what settings must be in the server to connect to the external IP address !? As well as the settings of the router.
I apologize for the question, he had already been discussed at the forum, but I did not give it the results! I opened all the ports and configured the server, but enter into the game world, I can only! Other players can only enter to choose a character, and then when you select the channel freezes! Please tell me that I have not?

If someone has already set up to where WanIP tell what changes are necessary to enter.
Thank you for attention!
Sorry for my English.
