I will have shortly this problem: Currentrly I have 5 labs with about 8 machines each, and 5 servers. Except 3 dual hosted servers, that act as proxies, the hosts have only a local private address . The labs are all connected to a central switch (I have a couple of 108 m cables ... but all seem to works nicely ...). In a few months 2 of the laboratories will be moved to a diffferent, quite far, building. I will not be able to lay a cable, but i will have to resot to using "regular" (althought fast) internet, trought some routers. I can connect to those routers only machines with public addresses. I need for some reason to keep the subnet "unitary" so using the same subnet as today. I thought of using some sort of tunneling on VPN, with one machine on each end connected on a NIC to "public" internet, and with another to private network. I need, since all servers are on one ond, to allow also broadcasts . (so the two gateways at the end of connection would appear to the machines as one switch). How to do it?
