 Q: I'm using a blocked port and stuff doesn't work.
 A: don't filter the port, or use one that isn't filterd.
  There's nothing more that can be said or done by any d.net programs or
people that I can think of.  You could work around this by using one of
d.net's servers that work on port 80.  dnetc supports http proxies.

 It, if that port wasn't filtered, of course.  Ask your firewall
admin what ports aren't filtered, and use one of those.  (Or scan to find it
out for yourself.)  I would try the https port, since that'll be unblocked
or you can do an HTTP CONNECT to get a transparent 2-way connection through
the proxy.
