[Icecast] Using Icecast relay function with dynamic IP at remote source end

Wed Apr 19 23:33:19 UTC 2017

/I made an error, I swapped two diagrams, it should be this:/

Here's how I've been doing it:

BUTT ===> WAN ===> Icecast server

I thought I might try this instead:

BUTT --> localhost Icecast server ===> WAN ===> Icecast server
