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

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

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

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.

Yes, that's it. Replace 44.128.0.1. And 149.28.12.190 replace with your current ip on the internet. 169.228.34.84 stays as-is.
