Is it some port that it looks at? I define it as anything that is not linked via modem/other telecommunications option. Aka, buildings next to each other linked via a hub or switch would be local, but two buildings in different cities linked via sattelite communications are a wide area network. Win9x is throwing what are esentially 'are you there' packets onto the network. FreeBSD sees these with no local destination in mind so it opens up a connection to the internet for them to go out on. There is a way to block these in the PPP script, but I do not remeber the exact command. I do remeber that they come in on some weird port #138 and #140 I think.
