In Many-to-Many No Overload mode, the Prestige maps each ILA to unique IGA.
Server
In Server mode, the Prestige maps multiple inside servers to one global IP address. This allows us to specify
multiple servers of different types behind the NAT for outside access. Note, if you want to map each server to
One unique IGA please use the One-to-One mode.
The following table summarizes these types.
