Flat range of PAT ports for a PAT pool
8.4(3)
If available, the real source port number is used for the
mapped port. However, if the real port is not available, by
default the mapped ports are chosen from the same range of
ports as the real port number: 0 to 511, 512 to 1023, and
1024 to 65535. Therefore, ports below 1024 have only a
small PAT pool.
If you have a lot of traffic that uses the lower port ranges,
when using a PAT pool, you can now specify a flat range of
ports to be used instead of the three unequal-sized tiers:
either 1024 to 65535, or 1 to 65535.
We modifed the following commands: nat dynamic
[pat-pool mapped_object [flat [include-reserve]]].
This feature is not available in 8.5(1) or 8.6(1).
