I had gone through the more ‘manual’ setup of Tunnels and Access before. I did get stuck at one point and I did got help here and managed to get Access setup. My main worry was that it was going to be difficult to share that knowledge across extended teams.
The ‘Ridiculously easy to use Tunnels’ are a huge improvement. More detailed knowledge of how the tunnels work and are setup is still useful for debugging some cases, the general day to day use has become much easier so I have little remaining reservations about using this technology vs the alternatives out there.
