+

It's common that you have a protected Linux/BSD server that isn’t publicly +accessible. Typically, you may have what is commonly referred to as a +jump server or bastion server which is accessible from a public +network (sometimes this jump server would be in a DMZ, and also Linux/BSD), +you connect to this jump server first, then connect to the protected server +from jump server.

+

Sample setup:

+
+--------+       +-------------+      +------------------+
+| Laptop | <---> | Jump server | <--> | Protected server |
++--------+       +-------------+      +------------------+
+
+ +

You can connect to the protected server through jump server via ssh with +command like below:

+
