My Net powered by MS ISA Server

This is my Home Network. I'm running ISA Server 2k6 (yeah it's legal. I've got a TechNet subscription) on my central Server which is monitoring all incoming and outgoing traffic by providing firewall, intrusion detection and Proxy services. At the same time it's offering VPN via IPSec for my mobile devices while they're not at home over the internet, so I can surf using unsafe/untrusted connections. My wireless LAN is WPA2 encrypted, but in order to access the Internet or my wired network there again a VPN connection is mandatory. By altering the DNS entries in my wireless router it was not necessary to write separate VPN-Connections for each environment.
