I am facing this problem from last many days .. problem is
PPPoE connection established from 5C:26:1A:6a:00:cC
userlogged in, 0.0.0.0 from 5C:26:1A:6a:00:cC
detect UNKNOWN
: authenticated
: terminating… - could not determine local IP address
userlogged out, 0 84 56 5 5 from 5C:26:1A:6a:00:cC
: disconnected

i am using mikrotik RB 4011 router and authenticate my user from dma radius manager,
i already configured local ip in ppp profile but still problem is there.
