MORE INFORMATION
================


This error is a result of projecting or "plumbing" the new route into the route
table on the RRAS server for the connecting client. This only occurs when all
the existing addresses have been used at least once and the clients connecting
are actually recycling older, previously-used IP addresses.

Additional query words: projection
