aack. mistake that should be a netmask of 255.255.254.0 not 255.255.252.0.
The 3 covers 255-252 = 3 hence 0.0.3.255. So it should read:

access-list 100 permit ip 209.145.96.0 0.0.1.255 any

so it will 255-254 = 1

so that will cover just the two /24's. 

dumb mistake. Sorry for the bother.

Thanks
Keith
