I currently have an ISA 2006 server connected to my company's internet connection.
At the moment there is only a single NIC in the ISA Server and all it is doing it publishing Outlook Web Access and acting as a web proxy. All our client machines have the internal IP of our ISP managed firewall as their gateway address as there is a VPN we need to route across.
To lighten the load on our VPN I would like to route web browsing across a separate ADSL connection whilst retaining the proxying of the ISA server.
Is this possible? Can anyone point me in the right direction with regard to the NIC configuration on ISA and the routing?
