Our ISP has a service that is specified as being a "single computer". In other words, you should not be using NAT or distrabuting it over a LAN with things like winroute and D-Link 602's or WebRamps (or even FreeBDS and userland PPP!). Being a tiny ISP it is important to control bandwidth use and abuse. Customers dial into a PortMaster 2E-30, straight through a Dummynet, forced to a Squid Proxy (No direct port 80) and then through an IPFilter Firewall. The Dummynet, Squid, and IpFilter are all on different boxes connected to our LAN Hub. I am just looking for a way to trap one or two people who are sucking bandwidth across a LAN without paying their fair share of the costs. Any Ideas? Is it possible to see the MAC address of the orignal LAN card? Thank You, Love To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
