address binding.

global-address mask
View

Parameter
inside-start-address: Start address of an internal-address range.
inside-end-address: End address of the internal-address range.
global-address: Public network segment address.
mask: Subnet mask of the public network segment address.
Description
Use the nat static net-to-net command to create a static net-to-net NAT entry. When
the router translates addresses based on this type of NAT entry, it translates the
network address portion without touching the host address portion.
Use the undo nat static net-to-net command to delete a static net-to-net NAT entry.
The global-address can be any address. Then it will be calculated by combining with
the mask and the length of the mask.
