backtracking forged packets?

Howdy,

Can anyone suggest tools, techniques and helpful contacts for
backtracking spoofed packets? At the moment someone is forging TCP
syns from my address block. I'm getting the syn/ack and icmp
unreachable backscatter. Enough that my service provider briefly
classified it a DDOS. I'd love to find the culprit.

Thanks,
Bill Herrin
