ISR4451-X NAT not working

[#1]

Hi Guys,

Does anyone have experience configuring Nat on the new ISR's? I have the following setup:

LAN --> subinterface on ISR4451X in VRF A --> physical interface on ISR4451X in VRF B --> WAN

The LAN sub interface is the 'ip nat inside' interface and the physical WAN facing interface is the 'ip nat outside' interface. No matter how I configure NAT I don't seem to be able to get it to work - I don't ever see any translations or even any hits or misses in the 'sh ip nat statistics' output. 

Config is:

ip access-list extended INSIDE

 permit ip x.x.x.x x.x.x.x any

!

ip nat inside source list INSIDE interface gi0/0/2 vrf A overload

! 

int gig0/0/0.100

 ip nat inside

!

int gi0/0/2

ip nat outside

Thank you!

 Interfaces in your router must located in the same zone. But if you need forward and nat traffic with different zones, you solve this with ZBF. In ZBF create zones and write relationship with zones in different VRF( in both direction ).
