Internet Connection Sharing - Enabled but not working?

[AsPe Heat]

I connected two computers in LAN network and enabled internet connection and file sharing.File sharing works properly,but I have some problems with my internet connection.
Connection name on my Server computer is "Zona" and name of the computer is "Server".
I configured all IP addresses correctly and when I go to Network Connections in Control Panel on client computer,I see internet connection called "Zona on Server".
I can check its stats,connect it,disconnect it etc.,but I cannot use it (Internet Browser won't open pages).

Any tips on how to solve my problem?
Thanks!
