I have my own person computer running Windows 7 and another computer running Ubuntu Server 12.0.4. Currently, if I have a something running on Windows 7 (like, say, Tomcat), I can access it on the Ubuntu box using the router ip (something like 192.168.0.x) and vice versa. How would I go about making it so that the Windows 7 box could access the Ubuntu box but the Ubuntu box could not access the Windows 7 box? Basically, I want to allow the Ubuntu box access to the internet but not access to the other computers behind the router.
I tried to setup a firewall rule on the Win7 box (using Windows Firewall) that had a scope of local ip addresses of my Ubuntu box (192.168.0.6) and selected Block Connection but that didn't seem to make a difference.
