This is a port query

This is a port query.

The web page ip is 10.1.1.2:8080

Wowza uses 172.3.5.142

And the client IP is 102.50.3.5

102.50.3.5 <-> 172.3.5.143 has 1935 port open, but

In 10.1.1.2 <-> 172.3.5.143, only 8087 is open.

Even in this case, can the 102.50.3.5 client see the video provided by 172.3.5.143:1935 through the 10.1.1.2 web page??

Also, is it related to the CORS error?
Access to XMLHttpRequest at from http://172.3.5.143:1935/live/IoT.stream/playlist.m3u8 from orign ‘http://10.1.1.2:8080’ has been blocked by CORS
error appears.
