I have an unusual set-up at one of my clients which is causing an issue. They have a NAS to share files between three laptops when working on various remote sites. In order to provide wired/wireless connectivity between the laptops and the NAS, and to issue IP addresses, I setup a basic NetGear router to provide network/DHCP/Switch features. It is not connected to the Internet. When working on remote sites these three users may also connect to the client's ADSL normally via wireless (using a wired connection to the NetGear).
Once connected to both routers the users can access the NAS, they can also run their SonicWALL VPN client software and connect back to their own office but they cannot browse the Internet. I suspect that IE is getting confused at to which network to use. The NetGear will be issuing not only IP addresses but also setting itself as the gateway address and DNS server address fro the wired connection.
Is there any easy way to "force" IE to route via a specific connection, e.g. wireless?
