ip nat inside source static command w/redundancy and route-map not working

GW M · ‎03-30-2009

I have a 3745 running IOS 12.3. We are trying to enter this:

---------------

ip nat inside source static 172.1.1.2 125.254.1.1 redundancy HSRP100 route-map ITNAT

access-list 101 permit ip host 172.1.1.2 host 149.1.1.1

route-map ITNAT permit 10

match ip address 101

------------------------

We get an invalid command indicating that "redundancy" and the "route-map" may not be permitted in the "ip nat inside source static statement together. Has anyone run across this before?

AKAIK - route-map nat is not supported on the 3745, I know it's not supported on the 65xx.

When I enter in the command "ip nat inside source static ", I have the following commands to choose from:

extendable - Extend this translation when used

no-alias - Do not create an alias for the global address

no-payload - No translation of embedded address/port in the payload

redundancy - NAT redundancy operation

route-map - Specify route-map

vrf - Specify vrf

So.. it looks like it supports "route-map"

I hate to point this out - but just because the command is visible, does not mean that it will work or it's acutally supported.

I just check the cisco feature navigator and "NAT - Ability to use Routes Maps with Static Translations" is only availabile in

Ok. I understand. Would you happen to know how we could NAT ip address 172.1.1.2 to 125.254.1.1 only when the 172.1.1.2 source is trying to get to 149.1.1.1 without a route-map?

Mmmmm off the top of my head no - I would try a route-map first. Then I would see if it were possible to NAT closer to the destination rather than the source? if that is not possible - then I would consider to upgrade the IOS.
