Solved: Static NAT requirment

shahid_duet · ‎02-29-2012

Dear boss

I have a IP 192.168.0.1 and i NAT it to 172.25.40.1

like ip nat inside source static 192.168.0.1 172.25.40.1 as outsider can get 172.25.40.1.

Now i want to NAT 192.168.0.1 to 172.30.40.1 as both 172.30.40.1 and 172.25.40.1 get 192.168.0.1.

How can i do it ?

Thanking You

Yes you can. But depends on what version of IOS you are running. NAT with route-maps was introduced in 12.4(T) i believe.

access-list 101 permit ip host 192.168.0.1 host x.x.x.x

access-list 102 permit ip host 192.168.0.1 host y.y.y.y

route-map NAT_25 permit 10

match ip address 101

route-map NAT_30 permit 10

match ip address 102

ip nat inside source static 192.168.0.1 172.25.40.1 route-map NAT_25

ip nat inside source static 192.168.0.1 172.30.40.1 route-map NAT_30

Test this out & let me know. Replace the x.x.x.x with the destination X & replace y.y.y.y with destination y

Hope you got it.

Vivek.
