    Proper EC2 Security Group Ports

    in AWS FreePBX

    In order for AWS FreePBX to function properly, a number of ports need to be accessible from the outside world. These include ports for things such as the SIP signaling and web server. In order to help clarify things for those with existing instances, if you have changed your Security Group and want to revert to defaults, or if you are simply unsure what all these ports are for, this page will outline our default Security Group/open ports for AWS FreePBX for your reference.


    Your EC2 Security Group for AWS FreePBX should look like the following by default. Note that we are only concerned with the Inbound tab and that the "Source: 0.0.0.0/0" is the "Anywhere" option when editing the rules:



    PBX Admin Access



    PBX SIP and IAX Communication



    PBX User Control Panel (UCP)



    PBX Phone Provisioning and Phone Apps
