Should run fine as it does with an icecast server running on localhost.
Instead I get buffer underruns

When I send the opus stream to my icecast running on localhost, everything 
works fine. When I send the exact same stream to my icecast server in the net, 
then buffer runs empty.

When I send an mp3 or aac+ stream to this server on the net, everything works 
smoothly, so network should not be the cause. Ping response time from this 
server is ~30ms, (a.k.a. "whoa, great!")

I don't see any differences betweetn the setups beside one server running on 
localhost and one on a remote host.

Interesting.  When I originally tested this, I didn't run into this problem 
(and I tested with a similar setup--remote icecast server).  I have a list of 
other enhancements from the Opus developers, so I'd like to come back and 
revisit this.

As a hacky solution, maybe you can use an icecast instance locally, then use 
icecast's rebroadcasting feature to send it to the remote server?  I wonder how 
well that works.
