BI-DIRECTIONAL STATIC NAT NOT WORKING

[zGomez]

Hi,

I have the following situation I want to do a bi-directional NAT for a complete subnet range.

I want to translate 192.168.96.0/24  -->  10.196.96.0/24 :   

   192.196.96.1  --> 10.196.96.1

    192.168.96.2 --> 10.196.96.2

... 

And this in both directions.

When i select bi-directional nat on the NAT policy it is not working for the inbound direction.
screenshot is not corrrect orginal rule has bi-directional set to yes

When i create 2 seperate rules it is working:

With the bi-directional it is not doing the nat.  What am I doing wrong on the bi-directional nat?

I actually like it more when i create seperate nat rules because then you have control over the source zone and it is clear from policy.

But i just want to understand why the bi-directional is not working.

bi-directional creates 2 nat rules behind the scenes and you can see both of them in cli.

Usually bi-directional messes up zone names so you should never use it and create 2 separate rules instead.

"Note: The destination NAT rule that is created in a Bi-directional rule, the Source Zone and Source Address in the original packet will be ANY. This can break some traffic if the rule is set up as a Static Source NAT with Bi-Directional. For granular control over the Source and Destination NAT rules, create them separately. This may be necessary if the Bi-Directional NAT is not working in a given configuration."
