How to enable NIV hairpinning on Cisco 4221 ISR?

[murindagomo]

Hi all.

I have a Cisco 4221 ISR which does not accept "ip nat enable" command on interface configuration.  Below is its IOS version. What can I do to get this command?

Cisco IOS XE Software, Version 16.06.03
Cisco IOS Software [Everest], ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9_IAS-M), Version 16.6.3, RELEASE SOFTWARE (fc8)

Thank you.

Look like the feature not supported IOX XE when I looked, feature navigator :

I think the ISR not support NVI 
can you check VASI feature, 
this feature can give you virtual-interface you can use it as IP NAT inside/outside for hairpin. 
I try this config in  CSR1000v with IOS XE.
