Hello, Finally there is a site with up-to-date information and people who know what they are talking about. THANKS I have a network with 2 class c addresses (x.x.166.x & x.x.167.x) at a college. Currently, we have a Cisco router with an ip of x.x.166.254. Is it possible to incorporate a Linux box running iproute2 for traffic shaping purposes, without changing my default gateway on each client (about 500, which are not using dhcp)? Also, are their any issues that may come up with the 2 class c's. Thanks for any info you can give. Chris G.
