ip nat ... extendable

Kevin Dorrell

Level 10

Can someone explain to me (or point me to a reference) what the extendable option does in an ip nat command? For example:

<b>

ip nat inside source static tcp local-ip port global-ip port extendable

</b>

The doumentation says:

extendable : "(Optional) Extends the translation"

which is about a much use for understanding as a bicycle is to a fish.

Hi Kevin,

I think this links can explain more http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a0080091cb9.shtml

..and Example 4-29 http://www.ciscopress.com/articles/article.asp?p=25273&seqNum=4

I use this in one implementation with the following ambiguous translations;

ip nat inside source static tcp 10.168.88.2 7002 192.168.88.2 443 extendable

ip nat inside source static tcp 10.168.88.2 1415 192.168.88.22 1414 extendable

Regards,

Dandy
