You need to find your public IP by going to   http://www.whatismyip.com  which will display the current public IP. Then you also have to set up port forwarding on your network's router for the port ranges required for your game. If it is a corporate network I assume this is not a possibility. If you do have access and permission to make changes to the router you can find instructions for the router and your game at:

How to use NAT
0
Rob WilliamsCommented:
NAT is likely already enabled on your router but configuring it any further would require access to the router. Do you have access ? If so let us know what make and model and we can fill you in as to the details.

NAT essentially translates the public IP address of you firewall for inbound packets...  Example is your IP address is 1.2.3.4 and the port for your game is 1234 so you setup your firewall to forward port 1234 to your private IP address, say 10.0.0.5.  Then you tell your friend to put your public ip address, 1.2.3.4, in his game connection settings.  When it goes to establish a connection, your firewall will receive the packet destined for 1.2.3.4:1234 and translate it to 10.0.0.5:1234.  When your game responds it will translate the from portion of the IP header to 1.2.3.4:1234 again.  You friend may need to do the same.

That is the birds eye view.  If you specify the type of firewall, we can help you with specific details of how to configure it to do this.

Hope this is helpful,

If it is a home router, you could also temporarily plug the internet connection straight into the console, and circumvent the router.

DMZ may also be another part of the solution if you must remain behind the router.

if it is a work router, the IT staff may be able to assist you, but may be unwilling.

but if you get in tight with the Network Admins, maybe they will let you stay and play games with them on the lan after work.
