Need help set up server

[ziejedaarwel]

hi guys,
I need some help to set up my SRCDS server.

I downloaded the hldsupdatetool i made a shortcut with command line etc like in the tutorial then I made an short cut to SRCDS.exe with in the command line:
D:\SRCDS\srcds.exe -console -game cstrike -tickrate 33 -maxplayers 6 +map de_dust2 -insecure
I also added the Mani Admin Plugin.

So now i click the short cut with the commandline. then its start up just normal. if it started up I can connect to the server and just play and use the Mani Admin Plugin but when my friend wants to join it says "Server is not responding"

Can someone help me with the next step to do because i dont have a router but just an normal modem so i dont need to portforwarding (right?) but dont know what else.

I hope someone can help me.
btw Soz for my bad english

Open a command line and type on: ipconfig /all
Copy ALL of it here. Don't edit out anything please.
