Start by making sure your RAS users and direct customers (your network's edge) can only output packets that contain their valid source address. If everyone did this, all of the world's problems would go away; Ozone depletion, world hunger, that silly rain forest thing, Smurfs and DoS and maybe even Microsoft! :-)
We prevent ANY packets to or from our network with a broadcast address. We don't filter on a per-machine basis for address spoofing, but ALL packets leaving our network must have a valid address on our network. Basically, one user on our network can spoof another user on our network, but no users can spoof addresses that are not on our network. --Eric -- Eric Wieling (eric () ccti net), Chesapeake Communications Corporation Sales: sales () ccti net 504-585-1850, Support: support () ccti net 504-535-5449 We have changed our name!
