Google isn't my friend with this long term issue which is up to date for my upcoming holidays again.

It would be great if you could provide a road warrior setup for DNS as well as IP tunneling as a backup solution.

Keywords are: iodine (DNS) httptunnel (IP) and maybe these programs for the port knocking(?):

fwknop-apparmor-profile, fwknop-client/server, knockdd (IP and DNS)

I would also really appreciate any hints to howtos or other tutorials or best practices.

Thank you in advance.

IP Tunneling could be achieved by a PPTP VPN. DNS by BIND and if you want to use Iodine, by using a second VPS. Port knocking is then used to secure the setup. All of these topics are well documented: Port knocking: I'd recommend only setting up the daemon on a port knock for additional security.
