How to route packets once tunnel is setup

Yes, this is a general networking question, so you're probably better of at stackoverflow or so -- this is not a network support forum, and there's not so many people reading this. :) Don't forget to include the output of ip addr and ip route show in your question.

Tunneldigger is not a ready-made VPN solution, it's a low-level part of a bigger networking stack. If you just want to tunnel, I suggest you go look for something like OpenVPN that doesn't require you to assemble all the pieces yourself.

tunneldigger is not OpenVPN. All it does is provide a layer 2 connection -- like plugging a cable between two computers, but neither end has DHCP or anything like that. OpenVPN takes care of IP assignment and routes, including "how do we route everything through the tunnel without trying to put the tunnel through the tunnel". You will have to manually assign IP addresses on both ends, set up routing through the tunnel on the client, and enable forwarding (and probably NAT) on the broker.

I can't close issues here though, so I'll let someone else do that.

Thanks for providing a reply here, @RalfJung. I will be closing this now. Maybe we should have documentation for some common use cases like this though.

Or, maybe somebody can create an Ubuntu network manager UI which just does everything for you. :-)
