Hi! I Have time warner cable business class.. I've noticed whenever high amounts of bandwidth are used, my internet goes down for around 2 minutes. Im wandering if there is any way to prevent this. All I've noticed in my firewall (which is a commercial firewall) logs are port scans and unhandled ip6 links. I Think it is something to do with my ISP. Any replies would be appriciated!

IP6 should be normal, all ISP are moving that way, port scans, unless excessive to a point of a DOS, again is something that happens to anything that's exposed to the "wild."

Since you have business class, a selling point of such service is that you can actually call the ISP and somebody who actually knows things will answer the phone. Do that.

I Used to have and i quote from the firewall log, "Unhandled link-local or multicast IPv6 packet dropped". sometimes 4 times a second, other times once every 19 seconds.... I Also Had, "Possible port scan detected" on ports "UDP scanned port list, 30325, 43205, 15288, 10212, 34314, 25247, 34322, 34325, 34323, 34324" Now im getting "
Possible UDP flood attack detected " Once every 5 seconds which i think to be a ddos attack.. All these things happened but not at a time... So it leaves me to think its just because of the things i do and its the isps problem.. I Will call TWC though. Thanks!

The first one is like due to junk traffic coming from a machine on the lan side of your network. Port scans are not all that uncommon but running a torrent client or skype can cause those also.

A UDP flood attack generally is a real attack...although it can be caused if you run torrents and the client crashes with open transfers.

It depends how much traffic it is. If it is enough to use up all your bandwidth then the internet may appear to go down for you. In most cases though the firewall is doing its job and just dropping the traffic as long as it is not a real lot you may get a little slowdown when it occurs.

True DoS attacks you and the ISP in most cases can do nothing to fix. The ISP would need to have a firewall configured to prevent this and some can not easily be differentiated between a valid torrent download and a attack. Generally the ISP ignores this problem because of the cost of a firewall that could process traffic for all their users.

True firewalls tend to cry wolf a lot so you have to generally use other tools to be sure it is a not a false report.
