I have an RB2011 and 3 host machines. Port six is connected to a PPPoE Server I would like ports 7, 8, and 9 to each have their own PPPoE connection (each one will have a different username and password) and provide NAT/DHCP to whatever it plugged into each of them.
I´m not sure if understood correct.
at ether 6 you have a pppoe-client to another pppoe-server
at ether7-9 you want to run a pppoe-server for hosts to dial in at your Mikrotik?
If each host should only be able to dial-in at one specific port only, you need three pppoe-server, three profiles and each secret assigned to the specific profile.
