It would prevent simple spoofing, yes, but that would not eliminate the Smurf attacks since to mount a Smurf attack you need to use the victim's address as your source address, and that one *is* typically "valid" according to the criteria you mention above (?).
But the first router the spoofer hits would NOT likely point the spoofed address back to the spoofer. At that router this would stop the spoof. This is why the feature needs to be shipped on all routers and enabled by default. -- Phil Howard | no1way99 () no5place edu ads3suck () no8where edu stop5it0 () dumbads2 edu phil | blow0me8 () dumb6ads org ads4suck () noplace3 org stop3ads () noplace0 net at | die1spam () lame8ads com end4it12 () anyplace net stop9597 () spammer8 net milepost | stop5ads () no0place org end7it69 () anyplace edu a8b3c9d6 () dumbads2 com dot | die4spam () lame1ads net stop6it2 () no6where com suck3it1 () spam2mer org com | stop9915 () spam6mer net stop1it8 () nowhere2 org stop0ads () anywhere net
