I have 3 mikrotiks A,B,C mikrotik B can see both A and C. B has a internet connection and C has a internet connection, currently all users use the internet connection on B . Is it possible to set up a user(PPPOE) on A that will use the internet connection on C. All users are PPPOE, B has a 5Ghz backbone to both A and C. All routers and clients can ping all routers and both gateways on B and C.
