ECMP load balancing - radio live stream doesn't work

Hi all,

At work I’ve setup ECMP load balacing with 2 providers. I don’t understand why but some radio stations won’t play at work, but work just fine from other networks, for example at home where I have just one providers. What could be the problem and how to fix it? Thank you.

For example this radio station works just fine at home, but I can’t even download the m3u file at work.

Solved it.

I had a port forward rule using port 8000 enabled.

/ip firewall nat add action=dst-nat chain=dstnat disabled=yes dst-port=8000 protocol=tcp to-addresses=192.168.0.250 to-ports=2135

Disabled it and everything works now.
