[kwlug-disc] Remote access to machine behind CG-NAT

[Khalid Baheyeldin]

No success with DNSMasq so far ...

I watched Lori's 2020 presentation, but its focus is on TFTP,
not DNS, which is a different use case.

The I followed this short tutorial:

https://dev.to/joeneville_/dnsmasq-lightweight-name-resolution-for-your-lab-2gim

I disabled systemd-resolved, and removed /etc/resolv.conf

Using this in my /etc/dnsmasq.d/local.conf

bind-interfaces
bogus-priv
domain-needed
no-resolv
no-poll
domain=home.priv
local=/home.priv/
expand-hosts
server=9.9.9.9
server=1.1.1.1

So there is no DHCP at all.

I tried adding:
listen-address=127.0.0.1

Didn't make a difference.

I tried restoring systemd-resolved, and replacing the two upstream servers
with it, like this:

server=127.0.0.1#5353

In all cases, no DNS locally, or from Wireguard peers.
