need the guide to user bbb server by using port forwarding form cisco or mikrotik router

[Krishna Thapa]

 am using BBB server for intranet with ip 192.168.100.50 and works fine. now I need to access this bbb form outside form internet, for other serivce i can simply use by port forwarding in my router but in the case of BBB i cannot use the service after simply port forward. However, i can access the front page of bbb but after click the join, the services need the local ip which wont reachable. 

Could the BBB server can be access via port forwarding? if yes, i need the configuration guide.

Thanks

HI Fred,

Thanks for the reply with link. I follow the link and configure the BBB but still some error occur. before i could not forward the port but now i able to forward and get the home page of bbb but after join the error message was change with Status Code 500 which i send you via attachment with name Error1.jpg and Error1_2.jpg.

I also attach the mikrotik port forwarded in the name of  "Nat enable in Mikrotik router.png"

and the details test provided by command "bbb-conf --check" in the name of "setip by public ip.jpg".

i could not figure out the status of problem, however may be i understand that my port 80 was forrwarded and it's work but after click join it need another more port to open which was not in the list, if so could you suggest me to the next steep to solve the problem.

I remain ..

Thank you agian.

Hi Krishna,

To summarize, these are the broad steps you need to do

1.  BigBlueButton must listen to the external hostname (not IP address) of your firewall.  For example, if the firewall has an external hostname of firewall.host.com, then when it forwards the request to the BigBlueButton server, the BigBlueButton server must listen for request to firewall.host.com

2.  You must access the BigBlueButton server using the external hostname from both internal LAN and external to the firewall.

3.  You must forward the ports (both TCP and UDP) from the firewall to the BigBlueButton server (I'm not familiar with your firewall)

The screen shots you showed have BigBlueButton configured to listen to an IP address.  This will not work if BigBlueButton is behind a firewall.  You must have BigBlueButton listen for incoming requests on the hostname (not IP address).

Recommend you refer to the FAQ entry again and follow the steps.  The above are the broad concepts.

Regards,... Fred

Hi Fred, 

Thanks. But i can access the home page of BBB. the port 80 was able to forwarded. the rest of other probably 1923,9135, need to pass inside port 80 which i unable to configure that however i open the all TCP and UDP port. 

any way, let's try it also. Is dynamic dns is useful to the bbb server?

Yes, as it will let you setup a hostname for your firewall.

Hi Fried, 

YES!

Thanks and I am able to use the bbb form intranet after using dynamic dns. It works and also no need to forward any other port except 80. Thanks a lot.

Hi Krishan,

While BigBlueButton does work through only port 80, you don't want to try and run too many connections that way.

When tunnelling (you'll see the words [ Tunnelling ] in the lower right-hand corner), the BigBlueButton client makes about 10 HTTP requests each second to keep up with the sessions.

As you add more clients, at some point, depending on your firewall, network, and BigBlueButton server, the increasing HTTP connections will not all be services.

Once the BigBlueButton server is unable to keep up with the incoming HTTP connections, the clients that are tunnelling will start to drop.  (They will get a message saying "you have been disconnected")

So, HTTP tunnelling is good for the few users that can't connect from their location (usually because they are behind a firewall themselves and can't make a direct connection to port 1935).

For running a BigBlueButton server, however, you definitely want ports 80, 9135, and 9123 open to the internet so all clients can connect directly.
