You mean this example? Do I need to replace 44.128.0.1 with my allocation?

Oh I see. I guess that is the real problem. I have not followed this guide. See the
section about rc.local. you will need to run the "ip tunnel" command to create
that interface. And pretty much everything in between.

Could you describe your interfaces then?
If you have just ens3 for ham and lan subnets then the easiest way to add an IP using the
Debian/Ubuntu interfaces file would be:
auto ens3:1
iface ens3:1 inet static
address {my allocated IP}
netmask 255.255.255.252

ens4 is not a physical devices. It is latched onto ens3 as a virtual device.
I tried to put ens4 on both lines and got error “Cannot find device "ens4"”

If this is verbatim then the issue is that you used ens4 in one line and ens3 in
another.

I am trying to configure the tunnel on Ubuntu 18 on a cloud VM just to figure out how the
configuration works.
I am looking at
http://wiki.ampr.org/wiki/Ubuntu_Linux_Gateway_Example<https://nam10.saf…
and have trouble configure the interface.
I have configure
auto ens4
iface ens3 inet static
address {my allocated IP}
netmask 255.255.255.252
However, the ifup ens4 command will failed to bring up ens4 interface. And of course
when running ampr-run.sh and find_pass.sh will resulted in Setting SO_BINDTODEVICE: No
such device.
Any advices on how to set it up on Ubuntu 18?
Thanks
Kun
