Enumeration
Pooling behavior is the policy used to select the address
for a new port mapping within a given address pool to which
the internal address has already been mapped.
arbitrary(0) pooling behavior means that the NAT instance
may create the new port mapping using any address in the
pool that has a free port for the protocol concerned.
paired(1) pooling behavior, the behavior RECOMMENDED by RFC
4787, REQ-2, means that once a given internal address has
been mapped to a particular address in a particular pool,
further mappings of the same internal address to that pool
will reuse the previously assigned pool member address.
