SSH jump host

I am using a server in my tinc to jump inside a private network that is behind a NAT router.

Using ssh commandline:

ssh -J 10.1.7.25 root@192.168.1.44

Where 10.1.7.25 is the jump host and root@192.168.1.44 is the server in the private network.

Or by using the .ssh/config file

Host jump
  Hostname 192.168.1.44
  User root
  ProxyJump 10.1.7.25

And call this using ssh jump.
