Network Address Translation Rules
Translate to Interface
This area shows the interfaces from which packets with translated addresses exit
the router. It also provides fields for specifying the translated address and other
information.
Outside Interface(s)
If you chose From inside to outside for Direction, this area contains the
designated outside interfaces.
Type
•Choose IP Address if you want the address to be translated to the address
defined in the IP Address field.
•Choose Interface if you want the Translate from address to use the address
of an interface on the router. The Translate from address will be translated to
the IP address assigned to the interface that you specify in the Interface field.
Interface
This field is enabled if Interface is chosen in the Type field. This field lists the
interfaces on the router. Choose the interface whose IP address you want the local
inside address translated to.
Note If Interface is chosen in the Type field, only translations that redirect TCP/IP
ports are supported. The Redirect Port check box is automatically checked and
cannot be unchecked.
IP Address
This field is enabled if you chose IP Address in the Type field. Do one of the
following:
•If you are creating a one-to-one mapping between a single inside local
address and a single inside global address, enter the inside global address in
this field.
•If you are mapping the inside local addresses of a subnet to the corre sponding
inside global addresses, enter any IP address that you want to use in the
translation in this field. The network mask entered in the Translate from
Interface area will be used to calculate the remaining inside gl obal addresses.
