NAT on Cisco ASR920

How can i do NAT on cisco ASR-920-24SZ-M

[Philip D'Ath]

I think only the ASR920-12SZ-IM supports NAT.

I think there were some plans to bring it to the other ASR920's - but I'm not sure where this got to.

You could try seeing if newer software has added that feature but don't get your hopes up.

Hi,

WE have the same problem. All commands for NAT are on the asr920, but NAT is not working.

Can someone give some advice ? Is it possible NAT on ASR-920-24SZ-IM ?

Regards.

Hello...I have the same problem. Could you solve the NAT problem that you wrote before?

Hello,

I checked the release notes for the lates (Amsterdam 17.1) release, it looks like nothing has changed, and NAT is till only supported on the ASR-920-12SZ-IM.

Have a look at the excerpt from the link below...

Advanced Security
Small cells deployments face challenges on the security front due to their location. The model (ASR-920-12SZ-IM)
supports security services such as IP Security (IPSec), Network Address Translation (NAT), and Port Address
Translation (PAT) to help protect against vulnerabilities to subscriber traffic and the network. A built-in hardware
crypto engine allows the feature to scale and makes it ideal for extensive small cell deployments

That appears to be an old data sheet from 2015.  The latest data sheet has removed references to NAT.

Advanced Security
Small cells deployments face challenges on the security front due to their location. The model (ASR-920-12SZIM/ASR-920-12SZ-IM-CC) supports security service such as IP Security (IPSec) to help protect against

Also, I see no mention of NAT in the feature compatibility matrix:

I'd say if you need NAT, look for a different platform.
