Vladimir, we have sometimes seen very strange things with Windows and<br>
some firewall products doing deep inspection on traffic that's going to<br>
the internet at large - XML based content often triggers this. Could you<br>
make sure all firewalls are off, or try using SSL?<br>
<br>
You don't state which client you're using. If you can cut the code down<br>
to a small example which demonstrates this problem we can certainly take<br>
a look at that.<br>
<br>
We know of several clients who are publishing to Rabbit at high speed<br>
over a WAN - there is nothing inherently tricky here.<br>

</div>I have a suspicion this is a firewall issue - with your simple<br>
streaming, do I assume the data is all nulls, or random? And with your<br>
Rabbit tests, is the data XML?<br>
