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!
