SSH connections through Bastion time out

[danieladugyan]

Background

We have a bastion host, running the system Warpgate, that allows us to SSH to machines on our private network by authenticating with authentik. However, if you are inactive for only a short while you get the following message:

# Connection to bastion.test closed by remote host.
Connection to bastion.test closed.

Which is very annoying.

To-do

There is an issue in the Warpgate repo describing this. Start there, verify that we have configured our systems correctly, and if so, try to find a workaround.
