Creating Static Outside Source Translations

Less commonly used, outside source translation enables you to set up translation
between two non-unique or not publicly routable networks (for example, two separate
networks that use overlapping IP address blocks).
ip nat outside source static
Use to create static translations for a source address (or address/port pair) when
routing a packet from the inside network to the outside network, and to
untranslate the destination address (or address/port pair) when a packet returns
from the outside network to the inside network.
A static translation created with the ip nat inside source static command enables
any outside host to contact the inside host by using the inside global address of
the inside host. A static translation can be used by traffic that is initiated in either
direction
Example 1 Simple address translation
host (config) # ip nat inside source static 10.1.2.3 171.69.68.10
Example 2 Extended address/port translation
host (config) # ip nat inside source static tcp 10.1.2.3 15 171.69.68.10 30
Use the no version to remove the static translation and purge the associated
translations from the translation table.
See ip nat inside source static.
Use to translate the source address when routing a packet from the outside
network to the inside network, and to untranslate the destination address when
a packet travels from the inside network to the outside network.
Creates a simple (IP address only) or extended (IP address, protocol, and port)
entry in the translation table that maps the two addresses.
A static translation created with the ip nat outside source static command
enables any inside host to contact the outside host by using the outside local
address of the outside host. A static translation can be used by traffic that is
initiated in either direction.
Example 1 Simple address translation
host (config) # ip nat outside source static 171.69.68.10 10.1.2.3
Example 2 Extended address/port translation
host (config) # ip nat outside source static tcp 171.69.68.10 56 10.1.2.3 24
Use the no version to remove the static translation and purge the associated
translations from the translation table.
See ip nat outside source static.
