Purpose of a bastion server


What is the purpose of a dedicated machine/bastion into a network? I would think that if the bastion machine and the internal machine have the same credentials, then it seems that it is useless to have a door into the internal network. Am I missing something?

They can have separate / different login credentials, or they can have the same. Really the authentication and authorization could be configured however you want.

The main thing is that the bastion would have one port on one network and another port on another network, but without routing. So passing through it would be the way to reach the machines on the one side from the other. If you are using OpenSSH, then look at the -J option for ProxyJump.
