It will "expand" your translations for static natting.
Previously, when using static nat, the only translation you saw in "show
ip nat translation" was the ip address:
<inside global> <inside local> <outside global> <outside local>
This was static. So you don't know anything about which sessions is the
client using ? is he translating web, ftp, telnet ?? The router
translates all, but you don't see it.
If you use "expandable", this translation will be expanded to PAT
dynamically, so when the client sets up a session you will see in "show
ip nat translation":
<inside global> <inside local> <outside global> <outside local>
<inside global:23> <inside local:23> <outside
global:1233> <outside local: 1233>
<inside global:25> <inside local:25> <ourside
global:1345> <outside global: 1345>
Which gives you an indication of which sessions the client is using....

Geert

Can anyone tell me what the expandable command at the end of an IP NAT
inside/outside actually does? I can not find any good references on
Cisco and it seems to be a fairly new command. Thanks!
