My Sygate FW log tells me, My USRobotics modem/router (model 029106)
is trying to send me UDP packets from and to port 1900.
However, the destination IP(239.255.255.250) is NOT my IP address (in
192.168. range, on which I log) , and the destination MAC is also
unknown on mij intranet.
The traffic occurs on a fixed frequency, once in about 25 seconds.
The log shows it has already occured 700 times, since last log reset.
What is this all about ?
