Hi all,
Is it possible to do conditional destination NAT as follows:
IF
SOURCE = NETWORK X AND DESTINATION = IP ADDRESS Y
THEN
NAT DESTINATION IP ADDRESS Y TO DESTINATION IP ADDRESS Z
I've tried all kinds of NAT/access-lists/policy routing to get this working but
have run out of ideas...
thanks,
Andrew.

Hi Andrew,
In my opinion, I don't think it would be possible to do this.

Not sure if this is what you had in mind but take a look at: http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a0080087bac.html
eg.
ip nat inside source static 11.1.1.2 192.68.1.21 route-map isp2
ip nat inside source static 11.1.1.2 172.68.1.21 route-map isp1
ip nat inside source static 11.1.1.1 192.68.1.11 route-map isp2
ip nat inside source static 11.1.1.1 172.68.1.11 route-map isp1
access-list 101 permit ip 11.1.1.0 0.0.0.255 172.0.0.0 0.255.255.255
access-list 102 permit ip 11.1.1.0 0.0.0.255 192.0.0.0 0.255.255.255
!
route-map isp2 permit 10
match ip address 102
set ip next-hop 192.68.1.1
!
route-map isp1 permit 10
match ip address 101
set ip next-hop 172.68.1.1
Hope it helps.

I implemented this goal two years ago using a c3640.But when you route-map,there is some problem with the NAT for some applications.Maybe cisco i has fixed these bugs.

thanks Steve,
This is exactly what I was looking for. Now for the real challenge - getting an IOS upgrade through change control!
cheers.
