Unable to do static nat beyond /24 CIDR subnet AR120-S

Issue Description

The customer wanted to do one-to-one nat static using a /22 network class as global and /22 class as the private IP addresses.
Alarm Information

The customer did find that, when trying to configure static nat, the network mask range was : 255.255.255.0 – 255.255.255.255.

Handling Process

I double confirmed with the customer the request.
After that, I tested in eNSP this scenario and I encountered the same limitation.
As an workaround for this scenario, the customer can use dynamic NAT configuring 4 nat address groups  /24 and 4 access lists with the same network mask. I tried this scenario even in eNSP and it works. Please see below:
Unable to do static nat beyond /24 CIDR subnet AR120-S-2783129-1

Solution

Configure dynamic NAT configuring 4 nat address groups  with the netmask 255.255.255.0 and 4 access lists with the same network mask.
