The Ubiquiti community is pretty much the main source of information for all things Ubiquiti. But it’s identified as being used for STUN services, so you may or may not need it. I’ve generally seen this in relation to cloud controller configurations. I didn’t have it open, and things seemed to configure and run just fine. I’ve done some reading but haven’t actually tested this in some cases UDP port 3478 needs to be open. A INPUT -p udp -m udp -dport 3478 -sport 3478 -j ACCEPT A INPUT -p udp -m udp -dport 10001 -sport 10001 -j ACCEPT A INPUT -m state -state NEW -m tcp -p tcp -dport 27117 -j ACCEPT A INPUT -m state -state NEW -m tcp -p tcp -dport 8880 -j ACCEPT A INPUT -m state -state NEW -m tcp -p tcp -dport 8843 -j ACCEPT A INPUT -m state -state NEW -m tcp -p tcp -dport 8443 -j ACCEPT A INPUT -m state -state NEW -m tcp -p tcp -dport 8080 -j ACCEPT ![]() A INPUT -m state -state NEW -m tcp -p tcp -dport 8081 -j ACCEPT That’s how I originally discovered I was missing the UDP rule. If you are having issues with the controller finding your APs, turning off iptables to see if they are picked up is an easy place to start. The last rule, for UDP port 10001, is specifically for AP discovery. If you are installing the controller on a windows system, you may have to make changes or turn off the Windows firewall as well. The rules listed below should be all you need. It turns out I was missing a rule in my iptables configuration. But just update the version number in the wget call to download the latest UniFi zip package (currently version 3.2.10).Īlso, I had issues getting the controller to detect the AP. The instructions I used point to an older version of the UniFi software. ![]() You will want to make sure any instructions you follow use the latest version of the UniFi software. They have instructions for a bunch of systems, including Raspberry Pi, Windows and various Linux configurations. ![]() For a full list of installation instructions from the UBNT Community, check them out. For the UniFi controller software, I decided to try and get it up and running on a Linux (CentOS) VM I have running… After doing a little googling, I was able to find some easy instructions for getting everything setup.
