Hi! Need Help To Open Rounter

My server run as well at Local now, but when i try to open to Wan for my friend play together i got the problem.
The sever side run continued, but the client alway got "Can't connect the server"
I had changed IP in client to my Wan IP
And the server side (change in file.ini) i change IP also.

At the rounter i open 2 port: 3300 and 3550

Please help me.
Thank you

That happens only due to IP problems. Check if you hexed your friends client properly again and make sure the first IP's of the Login Server, Login Agent and Zone Agent are set to your WAN IP and also your Network is enabled.
