I’ve been warned about running PPPoE server on the “lighter” routerboards, as they’re not powerful enough.
What is the limiting factor, CPU or available memory for running the PPP package?
Does the load on the board scale up with number of clients all the way from zero, meaning an RB112 can handle just a few clients, or is this not worth trying?
CPU limits you - PPPoE uses a fair amount, and if you get simultaneous login attempts, the board can ‘freeze’ for a while & connection attempts may time out.
