In this example, all users must connect to the BigBlueButton server via the uniform resource locator (URL). The following diagram gives a typical setup with an external firewall (your setup will, of course, have different IP address and hostnames). If there is an IPv4 Network Address Translation (NAT) between your users and the BigBlueButton server, then you will need to first configure the firewall to forward specific TCP/UDP connections from external clients to the internal BigBlueButton server otherwise, users will not be able to access BigBlueButton. You don’t need to do any of the changes below.ĭon’t worry if your server’s IP address changes, BigBlueButton comes with a configuration utility called bbb-conf that lets you change all of BigBlueButton’s configuration files to use any IP address or hostname. If your server has eth0 pointing to the external IP address on the internet, and there is no external firewall in place, then the packaging scripts should detect this external IP address and configure BigBlueButton accordingly. This is because the packaging scripts automatically configure BigBlueButton using the first non-loopback IP address, whereas access to sensitive ports is blocked.Ī variation of this setup occurs when the server has multiple network interfaces, but the external IP is still the first network interface (such as eth0) picked up by the installation scripts. In this simple network configuration, BigBlueButton should work out-of-the-box after installation. Here is an example of such a setup with the BigBlueButton server having a (fictional) IP address 203.0.113.1 with hostname. Port-based access firewalling is implemented using UFW. The easiest network configuration for installing BigBlueButton is on a server that has a single external IP address and the server is on the public Internet (and thus directly accessible by your users). If you are a developer setting up BigBlueButton on a local VM for testing, you can skip this section. You should configure your firewall before Installing BigBlueButton otherwise, you may get errors during the installation and will be unable to test BigBlueButton after the installation completes. This document covers firewall configuration for BigBlueButton 2.2.
