This thread has long-since veered off-course.
To "Guest", my reply to you about BitComet is here:

Confirmed: BitComet cheats...and not in a good way!
Back on the original subject:
"Firewalled" just means something between BitTornado and the other bittorrent clients (the other peers+seeds+trackers) is blocking a connection. Being firewalled is sort of like a telephone that cannot ring. People call, you can't/don't answer.
BitTornado being firewalled is almost certainly not a fault of BitTornado -- it's something else, usually a hidden firewall program (maybe included with other software, such as antivirus software?) or NAT router (maybe hidden inside of a DSL/Cable modem?). Further up the line, your ISP could be blocking file-sharing traffic. Even the internet lines your ISP connects to could be blocking some file-sharing traffic! (AT&T was shown to be doing this all over the USA -- the small ISPs got blamed for it, and didn't know WHAT to tell their customers!)
Lastly, viruses and spyware can be messing up your computer so much that it's not working right. And the first thing they typically do is knock out your antispyware and antivirus software...quietly so you don't notice.
