I’m thinking about implementing the “3 dumb router” scheme to isolate IOT devices from the main network at church and also create a guest network (maybe that’s 4 dumb routers now). The problem is that we have 2 buildings. We do have conduit with a Cat5 cable between the buildings.
Does anyone have recommendations on a device that would take 3 or 4 Ethernet channels and mux them over a single connection, then de-mux at the far end, providing separate, isolated ethernet channels?
I may be able to pull in a Cat6 cable or consider a fiber optic cable.
