I setup dansguardian to filter inappropriate content on my Ubuntu laptop following this guide. Everything worked fine.

However, I have Windows desktop which has internet access through an ethernet connection with the laptop (the laptop is basically a wi-fi adapter), and I was hoping the same rules would apply for this traffic. Unfortunately, the desktop appears to still have unfiltered internet access.

Is there any way to force this shared connection to play by the same rules as traffic originating from the laptop itself (i.e. pass everything through privoxy/dansguardian)?
