[Icecast] port blocking/disruption i think

[Iain Mott]

hi list

this is as probably more of networking problem than an icecast problem but
it is related - hope people don't mind.

I've been running tests for a project that starts 20 August. I'm sending
stream from my audio software to a local icecast server, then relaying
this to a commercial shoutcast service.

Initially i was using 7000 for the relay port. Worked fine. Then one
morning after a 24h test, the relay started experiencing frequent
disruptions, sometimes every minute. I tried resetting everything to port
7001 it worked, but only till the next morning. Now every port i've tested
so far is disrupted including 7000-7004, 8000-8001 and 9000. Initially i
thought, oh well i can at least do a manual update of the ports or find an
external service that lets me do a scripted update of the relay port, but
this latest development rules that out.

I'm in China so choices of ISP are limited.

Is there anything I can do?

will paste an extract from a recent shoutcast logfile at the end.
