I have a home network set up with a Netgear wireless router. Router is connected to modem to provide internet to connected PCs. I use a PS3 to play movies and the movies are stored on a laptop which uses a server program to allow streaming the movies to the PS3. The only problem is the laptop also is vulnerable to malware, etc because it is connected by wifi to the router, which is linking the laptop to the internet. Is there a simple way to allow the laptop to connect to the router, but block the internet? Is this possible by just setting the Windows firewall on the laptop to block all incoming content, or will that keep the laptop from sending content to the PS3?

Thanks for any assistance.

A good anti virus/malware package should protect it from malware.

The easiest way is probably to setup a software based firewall and block all incoming traffic besides coming from the PS3. The PS3 probably sends some sort of keep alive traffic back to the laptop and if all traffic was blocked then it would not function properly.

More complicated stuff like VLAN's are not for the average user and most SOHO routers do not support them. So, your 3rd party firewall blocking all incoming traffic should do the trick.

D-Link does offer an inexpensive hardware solution which might be a good fit for some G2G readers.
