Hallo, i can not understand, what meanthe option "extendable" in the config:

ip nat inside source static tcp 172.16.10.10 5101 10.10.10.10 5101 extendable  
ip nat inside source static tcp 172.16.10.20 5102 10.10.10.10 5102 extendable  


www.cisco.com:
The extendable keyword allows the user to configure several ambiguous static
translations, where an ambiguous translations are translations with the same
local or global address.
ip nat inside source static <localaddr> <globaladdr> extendable


Do i have the option "extendable" because of 2 static nat policies with the same
global address (10.10.10.10) ?  

Thank  You!

 If you look at the "show ip nat translations" command you'll see the
output is a table with a bunch of fields per translation.

 An extended translation is one where all the columns are filled in so
we have enough information to tell which translation a particular packet
matches.

 Not all entries are extended so it's possible that one entry can match
several different connections if you will.

 That's my understanding. Extendable is just a way to tell NAT to
remember as much as possible about a translation.
