One of our customers has about 20 Windows based PCs and shares one broadband connection throughout the office. A new system is about to be put in place that dicates that they use a different broadband connection with the new system, and keep this system seperate from any existing setup (on a different subnet).
The problem that I have is that the users will need to have the facility to access both systems. At the moment they have a 192.168.1.x subnet (running a server for one system with a SQUID proxy server managing access to their broadband connection).
The current system and configuration allows access to their server and ordering through their web based system which is tied down to their static WAN IP address. The new system will use an alternative online ordering system which must be tied down to an alternative static WAN IP address through an alternative provider (can't use existing connection) and on a seperate network.
What is the best way to add another subnet to their existing network infrastructure that will keep the systems seperate, but allow the users to access the 2 different systems?
Apologies if there is ample information about this, however a quick search never brought any suitable information back, and this fairly urgent.
Thanks in advance for your help,
