    There is a typo error “Proxy Command ssh -q -W %h:%p vps1” => “ProxyCommand ssh -q -W %h:%p vps1”

    I still get prompted for password on the destination machine – even though I’ve got my key stored on the jumphost.

    This doesn’t work for me:

    # ssh -J jumphost desthost (asks me for password on destination host)
    

    This does work :

    # ssh -A -t -l user1 jumphost \
    # ssh -A -t -l user2 deshost

    Why not use a hardened Windows Server in the DMZ? Then, after you RDP to it (using a PAM account), you’ll have access to a Windows GUI, a web browser, puTTy for CLI, etc. Security is essential in a DMZ, but having access to a good tool set can help application admins with the services they need.

    Great article.

    But you have used host1 and host2 along the whole article while the image that explain this show Host A and Host B.

    I prefer ProxyJump vps1 => Simpler Syntax
