I have this network,
red - 3 computers with internet connection - every computer has its own different connection to internet (over VPN)
blue - proxy server, squid
green - computers in my local network)
Anytime are always 2 of 3 red pcs on and blue pc knows, which 2 blue pcs are currently online. Now, what I need to do is, how should I set blue computer to randomly send communication from green computers over random 2 red computers (which are online of course - for example this hour is online first and third red pc, in the next hour will be online first and second red pc).
Any idea how to do it? I prefer solution (as I said to randomly route requests through random 2 reds).
I thought I can reconfig blue squid each time and reload configuration. But this has bottleneck, when there are many requests from green computers, they could lost connection.
