I’m running two servers, a Perforce Version Control server and a standard HTTP web server for a CMS, each on separate droplets.
I’m quite unsure what I should be setting for firewall rules on each of these. For the web server I’ve kept pretty much the defaults, inbound SSH on port 22 and all outbound TCP/UDP ports, but I’m really unsure what to do for the Perforce server which connects on 1666. I read this thread which just has me even more confused: https://forums.perforce.com/index.php?/topic/827-ports-to-open-on-firewall/
Any help would be appreciated!

If you’re running a web server, I’d open ports 22 (SSH), 80 (HTTP), and 443 (HTTPS).
If those ports are blocked, you won’t be able to get in to your Droplet or receive standard web traffic. Console will still be available if you lock yourself out, though if you’re using SSH keys, Console won’t be an option as SSH keys won’t work there.
The thread you linked to isn’t stating that you’ll end up giving access to data, it’s stating that the port is not encrypted (but neither is port 80, which is why HTTPS goes over 443 if enabled).
So what can you do? You can limit what IP’s access the port – that’d probably be best in any case if it isn’t something you don’t want the public to be able to access. To do this, you’d need a static IP, or a VPN.
You’d whitelist the IP of the VPN, connect to the VPN and then connect on that port. If you aren’t on the VPN, then you wouldn’t be able to access that port (the same would apply to everyone).
You can whitelist multiple IP’s or IP ranges, so if you have multiple users that need to access that port, you can add multiple IP’s – though keep in mind, they need to be static IP’s otherwise you’re going to end up removing and adding IP’s often. It’s not an issue, just more of a burden since you have to keep up with everyones IP.
ah that part makes sense, did some further digging based on your comment and I think I’m getting somewhere. Thanks!
It’s saying that it’s unencrypted, yes, so you would need to secure things in some way. Are you needing to access it remotely (e.g. over public internet)?
The recommendation in the thread seems to be to set up a VPN connection and use that to get through the firewall and access perforce. This is a perfectly valid option.
I’ve not worked with perforce myself, I use bitbucket. Does perforce not support ssh, https, or some other secure method?
I guess I just have no idea what to set my firewall rules to with Digital Ocean for a Perforce configuration. The thread says it needs 1666, but then if I enable it I’ll end up giving access to some bad data.
Can you narrow the question? What about the linked thread confused you?
