I’m having problems on a few of my networks where the majority of users have migrated to Vista. The traffic sometimes doubles and Mikrotik is unable to identify it, if I set a Queue Per Interface the network simpply freezes.
i am using vista and haven’t noticed anything like this
Are you using Vista or are you managing a Wireless Network with many Vista Clients?
so as i understood, clients migrated to vista and vista is downloading 2 times more than any previous windows versions?
That’s exactly right, this is not a constant phenomenon, but since I started watching it happening (2 to 4 times a day), the symptom is a high bandwidth usage at a moment where the network freezes entirelly. It’s almost like if someone is sending a huge amount of data at once.
Like I said the only difference on this section, is the migration from XP to Vista, which started about a month ago and matches exactly when the problem started. We see peaks of traffic that does not match any of mangle rules in place.
add log rule, then identify what kind of traffic it is. Probably some kind of DDOS attack?
i havent looked at vista yet, but I believe they are using ipv6 tunneling. I imagine you could completely block communication to their teredo.microsoft.com servers so they can’t figure out what to do ?
To selectively disable Pv6 components and configure behaviors for IPv6 in Windows Vista, create and configure the following registry value (DWORD type):
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters\DisabledComponents
DisabledComponents is set to 0 by default. Set it to 0xFF to disable all IPv6 on the machine.
