I have very little knowledge about networking. I have an internet connection on my PC (running Windows XP). I've enabled internet connection sharing to other computers on my network connected using a WIFI router.
I want to block use of GMail (in general, specific domains) from other computers, but should be able to access them from my own machine.
I can't edit my hosts file because my machine too would lose access. I guess I need to configure my wireless router for that. But I have no idea how to do so. My wireless router is a Zyxel P-660HW-T1 v2.
I'd appreciate any pointers.
