that is possible to be done:

1. open the port 8088;
2. go Settings -> Web Controller, pick "LiveLan" and unpick the two options below "Restrict access to LAN only";
3. for security reasons, make sure you set a username and password and unpick all the settings like "Controller", "Shortcuts", etc... (keep LiveLan picked);
4. take a look on your ip address, so the external address will look like this:
http://YOUR_IP_ADDRESS:8088/livelan/stream.m3u8

this link above you can embed on your html player, so it can be played on your web site

im running a 24/7 webtv using livelan feature, you can access on the link below

first of all, i'm not a vmix team member, im just sharing my recomendations once i get them work for my own job... i am not responsible for damages or issues coming from this procedures below and vmix team also, they doesn't have official support for livelan feature to be accessed outside of local network, do it on your own risc.

3. things you need to care...

1. your internet speed;
2. your hardware capability;
3. your stream bitrate;

recomendations:

*obviously, 2000 connetions needs a very high end machine and a very large internet bandwidth... try to stream for social networks which is easier to share and to stream or rent some dedicated windows server for that;
*for your computer, do a speedtest.net so you can determine the maximum bandwidth you have available on your connection;
*remember to allways use ethernet connection for a more stable stream;
*now as an example, if you want to stream at bitrate 3Mbits/s and your internet bandwidth is something like 500Mbits... 500/3=166... let's take 160... this is the number of stable connections (viewers) that your internet connection is capable;
*the more you increase your bitrate, the less people your internet connection is capable to connect;
