I am searching for a way to connect two different buildings with one GB Ethernet Cable. On both LAN i have two different routers with different subnets that needs to be remain in the new building. The reason is that one LAN is to be used for VOIP and has its own router and internet connection.
Now the question: Is this somehow can be done with 2 VLAN switches ? Can i combine the 2 LANs into one output and split on the other end again?
Thanks for the answers.
