We are currently happily running a SBS2003 server, servicing approx. 60 clients, with dual NICs and an ADSL router. All is working perfectly. We now have a client that wants us to connect 20+ of our users to their corporate network, to access their internal databases. They have a Cisco VPN concentrator and are asking us to install a Cisco ASA 5505 VPN device on our network to enable this VPN connection.
My first question is where (physically) do we need to place this device? I am assuming it should sit in between the external NIC of our server and our ADSL router. If we do this how will it a) affect all our users currentt access to the Internet etc. and b) know how to route requests to the clients network via the VPN?
The above infers that there will be follow up questions so be prepared to earn your points! :-)
