I have a client who wants me to set some networking bits and pieces up for him. He currently runs Rumpus as an FTP server on his own, local MacPro that has dual ethernet adaptors, has a BT Business Hub Router that connects to a Netgear switch, and then 6 macs and a ReadyNAS connect to that switch. In the new office he's moving to he is having two ADSL lines installed. My initial thought was to put each router on a different subnet (so 192.168.0.x and 192.168.1.x), have one router connected to one ethernet port that would be used purely to serve his Mac internet and run his FTP server from, the other port connected to the switch so that he can use the NAS and see the other Macs. One factor that needs to be considered is that his other Macs need to be able to copy to the FTP. I could probably achieve this with an external IP but I want to do it locally. Is that all possible/realistic, and would there be problems with internet given that his Mac will be able to get a connection from both router one, and router two via the switch? Should both routers be plugged into the switch? You know when you've been thinking about something so much it starts to get confusing?! Have I missed something blindingly obvious?
