We have a client who needs the following arrangement.
1. There is 1 main server acting as a proxy server to the internet
2. There are a few other additional servers also acting as a proxy server / gateway (sharing internet connection) at specific period of times.
3. All computer connected to LAN will need to discover available proxy servers to go to internet without manually changing the internet options. If (2) is available then use one of those servers to go to internet, otherwise then use (1). If needed a client side software can be installed at each of this PC.
How can I implement this ? Is there any gateway software in the market that enables this ?
Please help. I can add more points if needed.
