NATing For Different Destinations

Ali Hazim
Level 1
Level 1

Hello Everyone, 

I want to create different NAT rules for the same source based on the destination. 

Assume that I have the private range 10.0.0.0/8 and I want to create two NAT rules as follows:
if range 10.0.0.0/8 wants to reach ACL1 then use the public IP pool X
if range 10.0.0.0/8 wants to reach ACL2 then use the public IP pool Y

I've tried to create two "ip nat inside ..." statements, but it has no effect

How can I achieve this on an ASR1006

Can post full config related to NAT config and let us know what IOS XR code running :

basic config should work as below :

Example1 - single wan interface:
ip access-list extended ACL1
permit ip 10.0.0.0 0.255.255.255 x.x.x.x
ip access-list extended ACL2
permit ip 10.0.0.0 0.255.255.255 y.y.y.y

ip nat pool NAT_ACL1 x.x.x.x  x.x.x.x prefix-length xx <type match-host>
ip nat pool NAT_ACL2 x.x.x.x  x.x.x.x prefix-length xx <type match-host>

ip nat inside source list ACL1 pool NAT_ACL1 <overload >
ip nat inside source list ACL2 pool NAT_ACL2 <overload >

Example2 - Dual wan interface:
route-map NAT1

match ip address ACL1
match interface (wan1)

route-map NAT2
match ip address ACL2
match interface (wan2)

ip nat inside source route-map NAT1 pool NAT_ACL1
ip nat inside source route-map NAT2 pool NAT_ACL2

Note:
overload =
Applicable if to reuse nat pool addressing
type match-host  = Applicable if 1-2-1 matching of inside/outside addressing is required
