What the heck is going on, udp port 137

daniell
Astaro v8.03, Tons of packages blocked from my Computer 192.168.0.2  to the internal Lan 192.168.0.255 via the UDP 137.  
Have 47186 packages blocked this day..
Have checked and scan the PC for virus, but nothing..
My Packet filter log: 
17:33:17  Default DROP  UDP  192.168.0.2:  137  → 192.168.0.255:  137

Anybody can tell me what is going on.. ?

    Windows will broadcast if there's no AD controller, AND there's no Master Browser.

    Normally one windows PC will be 'elected' to Master Browser, but if there's only one PC on the network, I guess it might just keep broadcasting.

    I think modern versions of Astaro drop broadcasts, or have an option to do so; perhaps that option was changed by restoring the config.
