I don't know what it's like where you are fodder, (suprise!) but where i live you pay a tarrif for say 256kbps upload,, more for 512kbp, more for 1mb and so on up the scale. (Banding?) Download works the same way.
For ADSL here in .dk, it's the upstream that's (insanely) expensive. Typically the rates are like 8092/512, 4096/256, 512/128... for some reason I got 4096/512 though I was supposed to have 256, but I'm not complaining unless the bill is higher
I was really referring to the fact that some ISPs just block port 80 (HSF default) -- but it works for any port.
Haven't seen that - but most block incoming SMTP (some of them offering workarounds with some pointing back and forth between yours and their servers... still allowing you to run a SMTP server, but removing the possibility for open-relay exploiting).
I've heard that, in other countries, it's becoming common to throttle torrent traffic.rejetto:
Nice to see you here! Sounds good that uPNP is on the way, it makes things SO much easier for the novice users, and still easier for the power users (certainly a lot faster than entering router password, configuring, saving, ...). By the way, I've heard rumours that Microsoft's uPNP API doesn't always work properly, and the author of µTorrent told me he wrote his own code - just something to keep in mind / research before you spend time on the quirky MS API.
