Re: How to test how many connections are being reset by RST pack The problem though is whatever Comcast is doing to monitor P2P is resulting in serious latency crud for some of the rest of us who don't use or even have BitTorrent. 3 days straight I have had my cable modem here in the MD/VA/DC area literally bombarded with 6881 incoming port traffic (the log is long and glorious) - a reverse lookup on those IPs reveal cable modems from both comcast.net as well as other cable/dsl providers and our routes are toasted as a result. Comcast Tech Support knows about it and calls it "network maintenance" If they're going to use to such software and monitoring tools, perhaps they should at least configure it correctly.

What you are seeing sounds like "P2P Afterglow." »Re: Dangers of P2P filesharing networks?
Your firewall should be ignoring these packets. If they are causing latency, it probably is due to the number of CPU cycles that the router has to spend to evaluate or log them. It doesn't take any CPU cycles to drop them.
But if they really are causing problems, you can change your IP: »Comcast High Speed Internet FAQ »How do I get a different IP address?

said by dontask2much :Such connection attempts have never been a problem for me. And I often see them after I close a torrent. It sound more like your equipment can't handle the probes than that the Comcast network is suffering.

Also, I don't see how Sandvine can be a part of the problem. You shouldn't see so many BT connection attempts if you never use it. The peers only attempt to connect to a client which was part of torrent.
If I were a guessing person, I'd guess you have a wireless LAN, and an uninvited hitch hiker using your WLAN for their torrent sessions.
