Force all SSH connection through Jump Host

I want all my SSH connection go through a VPS so my IP address stay same even if my ISP changes IP. This help me to only access SSH access from my VPS IP address, this increase security as no one else able to SSH to the server.

To force all my SSH connection to use ProxyJump, i edit file

vi ~/.ssh/config

Added

Host * !ok.serverok.in !51.38.246.115 !192.168.1.?
    ProxyJump [email protected]:3333

In above Host * will match all hosts, so whenever you try to SSH to a server, it will use ProxyJump. I specified some host with !, this will exclude those host from using ProxyJump. One of which is the Jump Host itself, it is important you exclude Jump Host or it will cause a loop and won’t work. You may also need to add your Local IP address.
