Can someone explain to me (or point me to a reference) what the extendable option does in an ip nat command? For example:
ip nat inside source static tcp local-ip port global-ip port extendable
The doumentation says:
extendable : "(Optional) Extends the translation"
which is about a much use for understanding as a bicycle is to a fish.
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
