File lib/ippool.c:

Line 218:               dynsize = (1 << (addr.len*8 - addrprefixlen));
I always thought the "-1" is for the GGSN itself.  So if you have a /24 with 
256 addresses, one of the addresses is for the GGSN itself.  Then you may also 
want to exclude the network, gateway and/or broadcast addresses in addition.

However, the existing code would have mandated the GGSN to use the highest 
address within the pool to work.  All of those assumptions are bad anyway.
