IOS NAT vs IOS-XE NAT on the NAT Order of Operation.

Dear all,

 

I have been seeing the following information about NAT Order of Operation on IOS Software.

Howerver this doccument is not restricted to specific software and hardware versions so 

actually IOS-XE software such as ASR1K and ISR4K are included in this specification right?

Hi @mhiyoshi,

I would expect the order of operations to be the same on both.

Cheers.

Hello

What nat are you using or referring to? - Classic domain based nat or domain-less based (nvi) nat?


The former uses the order of operation you may be familiar with, however NVI nat is different in its route lookups, where it performs two of them pre/post translation

Re: IOS NAT vs IOS-XE NAT on the NAT Order of Operation.

Hello Paul,

 

Thank you for your advice, well basically I have been using classical domain NAT such as

Static/Dynamic NAT, PAT and so on.

 

However it might be helpful if there is evidence which IOS-XE NAT is equivalant to IOS-NAT provided by the previous URL.

 

Especially I am really taking care of the order of NAT process. ACL fast or Routing fast before NAT process etc depend on the direction and if there is difference between them, I have to tackle with such info.

 

Best Regards,

Hello

Well if your are referring to domain-based nat any changes to the nat order be it for ios /xe etc.. I would expect to be well documented by now if there were differences.



kind regards
