L2J Server

Hello everybody. I am a little new in this things but a long time ago I was able to create a server. The thing is that now I have another company with provides my internet and they have installed me a modem which has an internal wi-fi router and I can not modify any configuration of it, I have tried but when it connects to internet again the configuration they established is again in the configuration. I have also tried asking them to change it but they denied.

This is my modem: http://www.motorola.com/Video-Solutions ... G901_US-EN

I was wondering if it is possible for other PCs to connect to my pc while having this configuration. I created the server but they can not connect and maybe I have to put another directions in the configuration of the server. I will leave a picture of my connection details.

Please I need help ! I do not know what can I do !

If it is possible, I would like to make a server with your beta version. Sorry for no telling before.

Seriously ?, nobody can help me with this ? =S

Maybe your firewall/antiviru firewall blocking ports? Try to add rules or disable firewall.
