Servers Problem when trying to create Lan / Network for Games

Need for Speed ​​Most Wanted link

Community Hello to!
Well, today I come to see here because I've been burning the neurons trying to solve a big problem little while.

Like anyone, we want to grab the season to play something on the network.
BUT
The problem is that in trying to want to create servers, I am not able to get finished building the server.
Example: We have dealt with the Need For Speed ​​Most Wanted v1.3 and one way or another we could not connect to a server. When we create, see the poster of "Connecting ..." And nothing happens.

We have changed IP "s of our notebooks, ie
PC1: 192.168.0.1 Ip
PC2: 192.168.0.2 Ip

And nothing happens ...
In my opinion, I am more than sure that any configuration of the firewall may not be able perimiter create the server we are trying to establish.
We are also downloading Counter Strike, to see if the type of server that requires to know if we can activate it.
I expect a prompt response from the people aware of ports, network connections, or someone who has had this problem and been able to solve it.


Of course .. Thank you.
