How do I setup a tunnel piercing scenario on my Ubuntu client to access the internet through my own server including port knocking on it?

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.
