  • This line did it. I don't understand though... I went to the firewall gui and setup a rule to allow all traffic on port 22 within my LAN, yet that didn't do the trick. Is there a difference between ufw and the Firewall app that comes preinstalled with Mint? Commented Nov 26, 2020 at 12:25
  • One other thing, while this command allows ssh to work, I still get asterisks when I traceroute the server. Any idea why? Commented Nov 26, 2020 at 12:28
  • @Jeff That is normal, traceroute uses a different type of connection for its test, usually udp ports 33434 to 33534 or some icmp packages - which may be blocked inbound on the server (and/or outbound on the client). Feel free to ask a new question about that. Since ssh works for you now please accept an upvote the answer so that others who have the same problem can see that this is a solution.
