Configuring a Local and Global Address Range
The local address range tells the router which local unregistered host addresses to
translate into global addresses. The global address range tells the router which
registered global addresses to use when translating local addresses.You must
configure at least one local and one global address range.
You specify a local and a global address range as a base address and a prefix
length (from 1 through 32 decimal). The prefix length determines the number of
available local or global addresses. For example, if the base address is 197.1.2.0
and its prefix length is 24 (255.255.255.0), then the address range you specify
includes addresses 197.1.2.0 through 197.1.2.255.
To configure a local and a global address range, complete the following tasks:
