Duplicate IPs are indeed rejected for "server".  You may want to
investigate switching to "pool" commands from "server" for your pool
server needs.  "pool" spins up as many servers as needed to have
maxclock peers in the billboard (default 10).  Duplicate IPs cause it
to take longer to reach maxclock, but do not affect the ultimate
number of associations assuming enough non-duplicate addresses are
