How to set up access to the local BigBlueButton server from the Internet through Apache's mod_proxy on the gateway?

Question

Nginx

In the local network there is a server on Ubuntu with BigBlueButton (BBB)
​​WinServer2008 works as an Internet gateway, Routing (NAT) and TrafficInspector from above.
The task is to bring BigBlueButton to the Internet.
BigBlueButton needs ports 80, 1935 and 9123.
I passed the last two ports through portmaping.
I can’t port 80, because Apache is on the gateway with its own tasks, and it also needs 80.
I tried using Apache's mod_proxy, below is the setting (192.168.0.29 - the address of the PC with BBB in LAN)

<VirtualHost *:80> 
    ServerAdmin [email protected]
    DocumentRoot C:/Apache2/htdocs/bbb
    ServerName поддомен
    ServerAlias www.bbb.arhlib.ru
 
    ProxyRequests Off 
    <Proxy *> 
        Order deny,allow 
        Allow from all 
    </Proxy> 
 
    <Directory C:/Apache2/htdocs/bbb>
        Order Allow,Deny
  deny from all 
    </Directory> 
 
    ProxyPreserveHost On
    ProxyPass /	http://192.168.0.29/
    ProxyPassReverse / http://192.168.0.29/
 
    ErrorLog "C:/Apache2/logs/bbb.log" 
    CustomLog "C:/Apache2/logs/bbb.log" combined 
 
</VirtualHost>

As a result, opening the http: // subdomain opens the nginx page on which the BBB works (that is, it seems to go where it needs to).
But when accessing http://subdomain/bigbluebutton/ it gives a 404 error (from 404 nginx on this server)
At the same time, when accessing 192.168
.

listen 80;
server_name IP_server subdomain
;

Answer 1

Judging by

But when accessing http://subdomain/bigbluebutton/ it gives a 404 error (from nginx 404 on this server)

- proxy to nginx is normal, see settings of nginx itself (reading its logs can help)

Answer 2

Если доступ нужен до подкаталога на сайте, приведите конфиг к такому виду:

<VirtualHost *:80> 
    ProxyPreserveHost On
    ProxyPass /	http://192.168.0.29/bigbluebutton/
    ProxyPassReverse / http://192.168.0.29/bigbluebutton/
 </VirtualHost>

Именно к такому, уберите все остальное. Для проксирования этих строк достаточно.

А как быть если только вид кода вас вгоняет в ступор, как меня? Я установил BBB сервер версии 1.1 и теперь еще использую веб сайт createwebinar.com в связки со своим сервером бесплатно! Есть календарь планируемых и прошедших вебинаров, возможность скачать состоявшийся вебинар в формате MP4, запостить это видео на хостинге Vimeo. В общем очень удобная связка, рекомендую!
