I am looking to solve an issue where I want to disable IPv6 but keep LAN connectivity. I'm not really a network person, and my understanding of IPv6 is pretty scant. I'm assuming since many VPN clients offer the ability to disable it, and I don't really see it being used/discussed other than under security issues, that its worth disabling in some situations. Is it really OK to leave it on? I certainly don't want to become the victim of some new exploit or anything. But I need access to my LAN machines like my file/media server. Do I need to just set a local 192.x.x.x range in the Routing setup of the client, to keep them outside of the VPN? I don't really understand why disabling IPv6 would disable LAN access anyway, since those PC's have IPv4 addresses, right? Outside of this issue I'm also just generally curious how/why this is. I'm using Windows 7 Ultimate 64-bit.
