Beskrivelse    :

We and all our customers have Sonicwall as firewall, its TZ100, TZ110, TZ200, NSA200, NSA240 etc, all models off Sonicwall. All users that got this message has Windows 2008, 2008 R2, 2012, 2012 R2 with terminalserver and the TS-Gateway/RD-Gateway and RDWEB (RemoteAPP). Its only port 443 that is open in the firewalls, its forwarded to the TS-Gateway/RD-Gateway.

The strange thing is that all of ur customers started to get this message from ther ISP providers today. The ISP's got the message from norcert that is Norwegian version of NSA.

It looks like all that have a Windows 2008/2011 SBS servers with remote.x.x on port 443 (for mail, owa etc) also got the waring about amplification-ssdp. Is there something bad with Windows and SSL ????

Dont need to block anything. The only ports thats open is 443.
I did get an answer from Norcert where they tell me that something was wrong in there system. But i dont like that NSM (Norwegian NSA) is doing this type of active tests.
