I have a link of my own that refutes your theory thus far »
wiki.vuze.com/w/Bad_ISPs ··· _America Before jumping to conclusions, look at note 11 under unresolvable NAT problem for ADSL2+ HSI(which VDSL isn't noted to cause an NAT problem at all, neither is regular ADSL): "Note 11: The Motorola 2210-02-1ATT DSL modem (and probably also the other DSL modems that work with U-verse ADSL2+ HSI) does not have a bridge mode and is apparently overwhelmed by the different number of nodes communicating with your PC over DHT. Disable DHT as a work-around, and possibly also reduce the total number of connection allowed by your BitTorrent client to 100 or so." A better solution to me would seem to be to ask for a different model gateway. No idea why TWC is on the list of limiting BT bandwidth and unresolvable NAT problem, as a side note. I always get incoming connections and I can get full speed from Linux ISO torrents that I download and seed without a VPN. In fact, one reason I torrent them is that it's often the only way to max out my line on such downloads, which can be a few gigs(making you want to max it out), besides wanting to help the community.
