This will cause Barry to SYN-flood himself.
The only way to block it is with incoming filters.
If you block the outbound path back, you'll get SYNs, return SYN-acks,
but never get those ACKed...

Agreed. So, the question arises, why can't Barry do this? It seems
to me to be the logical solution, since the source address is already
known.
