I have been attempting to get a local computer running ElementaryOS set up as a remote server for the past couple days now. I made sure the UFW was turned off entirely for testing, I messed with my sshd_config, set up port forwarding and even tried to set it as the DMZ host on my router.
Finally, suspecting my router of being messed up, I set my macbook pro as the DMZ host and suddenly all my ports were open. (checking through canyouseeme.org)
So my issue falls back to the computer itself. Even beyond setting up the ssh functionality, I can't even get the ports to be seen as open when I have the eOS computer set as the DMZ host.
Does eOS have limitations when it comes to remote access? are there settings other than UFW to consider?
