Thanks a lot, Rusmur, for your response. I really appreciate it.

uTorrent uses only one tcp port for all its work. Yes, it does use a UDP port 
for DHT which, I didn't open in the firewall. Thanks very much for your 
insight.

I've configured my router to put my laptop in a DMZ allowing all ports to be 
allowed and thus the firewall controls the opening of ports....

Yes, I agree. But, compared to uTorrent, the memory Azures uses is too much. I 
needed a torrent client with a very small memory footprint and yet be full of 
features. uTorrent does that job very well. I can leave uTorrent running in 
the background and load UT2004 and play on ! :-)  This is something not 
possible with Azures as it takes up lotz of resources.

I still one question unanswered:

I would appreciate if it could be answered.

That was a comment I made on the documentation lacking the necessity to 
configure the system to start the firewall script automatically on each boot. 
Nothing critical.

Thanks again for you help.
