Recover server remotely if offline?

Recommended Posts

I had a problem the other day where my network connection went into a blocking state.  (This has now happened twice when I had wireguard configured, but I've not yet assigned blame - different story).

 

Luckily I was home when it happened overnight and so I could just go in and reboot manually via the gui in the server room.  But what would happen if this happens and I'm away on holiday?  The server does seem completely fine, except that I can't reach it via SSH or the WEB GUI.  Would a second NIC help to login via should the main enter blocking state?  Any ideas or suggestions?
