It's fairly typical for cable modems to use 192.168.100.1 for an internal interface and apparently some of them, e.g. the Motorola Surfboards, send out multicast probes. Here is a link to a thread where someone asks the same question: http://www.luni.org/pipermail/luni/2002-February/004419.html Bottom line, the source is your cable modem not the router, and it isn't anything to worry about. Hope that helps. --Brad _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink ------------------------------------------------------------------------ leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
