Can connect to server without problems if using my lan ip 192.168.1.100 and local ip 127.0.0.1 for host file client connection.
But cant connect if i use external IP 89.41.67.187 on host l2authd, client says "loggining please wait" forever.
What i did.

Proof:

using this tool http://www.yougetsignal.com/tools/open-ports/
result all ports are open.
And also turned off windows firewall and router firewall.

If your server can get external connection please post your login server screen and ipconfig.xml i will try another setups using working examples.
Thanx.
