Using SSH bastion also means having a strict IT security policy. According to the principle of least privilege (PoLP)giving minimum levels of access to a user or resourceeach machine within the private network should have an SSH configuration. Then it will initiate a second connection directly from the client to the target system via that tunnel. If you skip the SSH configuration step, you risk giving unrestricted access to all servers. the client system will initiate an SSH session to the bastion host and basically build a port forwarding tunnel.
