I'm currently using internet sharing to allow my parallels virtual machines to share internet access via the airport card. This works fine but interferes with my VPN access because machines inside our company are on a 192.168.2.x network and internet sharing is assigning the same range. On a normal DHCPD I could configure the address range to get around this but I can't see how to do this on my Mac. Anyone got any ideas? 😕
