If the spoofer is dialed up to YOUR network, and spoofs the address of someone else out on the net, then YOUR router should find that the source interface is not in the list of routes for that address, and discard it. If the spoofer is attacking YOU, then that means the network the spoofer is attached to is NOT blocking him by this method, but SHOULD. -- Phil Howard | [email protected] [email protected] [email protected] phil | [email protected] [email protected] [email protected] at | [email protected] [email protected] [email protected] milepost | [email protected] [email protected] [email protected] dot | [email protected] [email protected] [email protected] com | [email protected] [email protected] [email protected]
