AWS instances have private IPs that are mapped
(elsewhere) to a public
IP, at no point does the public IP/Network exist on the AWS
instance.
That was true for legacy EC2. Now days, instances are launched in VPCs
where you can choose to use your own public or private IPs directly on the
network interfaces. You can also now have multiple interfaces on an
instance.

The right question would be :
On an AWS instance, is it possible to have another public (non-
AMPRNet) IP, so that we can build a tunnel to where we want, and route
our AMPRNet subnet through it ?
Moreover, I never tried Amazon cloud services, but Microsoft Azure has
a built-in VPN system. It's possible to established IPSec tunnels
between Azure VMs and a local router. I saw Amazon has a feature
called "VPC" (Virtual Private Cloud). I don't know it it's the same
thing, and if it's suitable to connect AWS instances with local
resources via a VPN.
I think the general problems with doing any forwarding/routing on an AWS
instance is their layer 3 abstraction foo. AWS instances have private
IPs that are mapped (elsewhere) to a public IP, at no point does the
public IP/Network exist on the AWS instance.
