Does firewall on the server protects the client computer?

Hi everyone,

I have setup a simple peer to peer (connected directly by cable) network at my home:

Tha main computer: running Windows ME. PC-cillin antivirus and firewall installed. Connects to the internet via a 56K modem.
The client computer: A sony laptop, running Windows XP pro, no antivirus and firewall. Connects to the internet via the above computer.

Now my question:
Is the client computer (laptop) protected by the firewall installed on the main computer? If not, what should I do. Any ways other than installing firewall on the laptop?

I am willing to increase the points if the answer is needs to be comprehensive.
Appreciate your comments.

Hi onlyshiza,
Yes the client computer will be protected but mainly this is due to the internet connection sharing software you are using. With this software you have to configure every connection from the internet which is permitted to connect to the client PC so it is effectivly a firewall for the client pc.
Of course if the main PC gets compromised then so could the client pc so you need a firewall on the main pc aswell.

Thank you very much grblades. I just forgot to mention that I have changed the settings of the firewall option on my main pc to "allow my computer to be visible on the local network (NeTBIOS)". Does this this make the main pc more vulnerable?

No you are only giving access on the local network. You are not giving any machines on the internet any extra access.
