For your firewall settings, you will find everything you need here:

It is the common setting for most Tor operators.

Although, I don't think it is the source of your problem and I wouldn't worry too much about it unless it happens repeatedly.

The log in "/var/log/syslog" might give you some helpful hints.

Greetings, I was directed to this relay subscription by the owner. I've recently started my own relay and everything has went smooth for the first few days. Then the relay mysteriously went offline for a period of 8-9 hours. Happened while I was sleeping I think, but any rate it came back on after I restarted the tor daemon and rebooted the server. I'm starting to think my firewall configurations might have been the culprit, even though I ran a very rudimentary setup. Basically just: -A INPUT -p tcp --dport <my SSH> -j ACCEPT -A INPUT -p tcp --dport 9050 -j ACCEPT -A INPUT -p tcp --dport 443 -j ACCEPT -A INPUT -p tcp --dport 80 -j ACCEPT -A INPUT -j DROP

Default ACCEPT on OUTPUT

My ORPort is on 443, so I don't see how this could be interfering. I noticed my server reboot got rid of all my rules, so I'm thinking that could've been the issue. If so, what other ports should I add? Do I even need a firewall for the relay? I don't do anything else with that server, so If it doesn't need a firewall to stay secure I won't use one. One more thing, I had a flag on my relay that said I needed to "update the descriptor." It went away after rebooting my server as well, could that been the issue?
