BCP38 tester?

[frnkblk at iname.com (Frank Bulk (iname.com))]

The good news is that source address spoofing does seem to fail with most CPE's NAT.  

At the end of the day, just turn on uRPF and/or use ACLs.  It's amazing how much destination 192.168.0.0/24 and 192.168.1.0/24 our ACLs also block.

Yes, but penetration is a problem, which is why I was thinking about
people like YouTube, Ookla, and the like.

Any Flash app that lots of people run frequently.  Assuming those apps
could generate the packets, which, on reflection, I would bet they can't.
