Allow your subnets before the above rules.  Here's a sample rule:

-A INPUT -s 10.0.0.0/24 -p tcp --dport 22 --syn -j ACCEPT
# subnet    ^^^^^^^^^^^

You'd need one rule for each subnet.

   Awesome Mike, that worked like a charm.  Thanks!

Somewhat related question: would the same rules work for ftp attacks as well? Obviously replacing the port number with 21, but would they work? Duplicate the lines, replace port and hope that ftp also gets curbed the same way?
