Can I provide external access to a BigBlueButton server behind my firewall?
Yes. A typical scenario is you have BigBlueButton running on an internal computer behind a firewall. You have defined an external hostname, such as external.host.org, that will resolve to the IP address of your firewall. You want external users to access BigBlueButton using that hostname. First, on your firewall, you need to forward three ports to the the internal IP address of the BigBlueButton server. These ports are 80 (HTTP), 9123 (Desktop Sharing), and 1935 (RTMP). Here is an example of forwarded ports on the D-Link DIR-665 router (the internal IP address of the BigBlueButton server in this example is 192.168.10.198): Next, when the firewall forwards incoming requests to the internal BigBlueButton server at 192.168.10.198, the BigBlueButton must be listening for these requests. The HTTP headers will identify them as for the server external.host.org, so you must tell BigBlueButton to listen for incoming requests for that hostname (not the internal IP address).
