I know this is a really complex subject and may be impossible ?
If you could limit connections based on unique source ip address rather than the
current specific ip address you could implement fairly powerfull DOS rules..

i.e. limit ANY 1 source ip address to 5 connections per second
Therfore no individual ip could DOS you, and DDOS would be slowed down

I know this would take up a large amount of memory and hit performance hard but
I'm sure that could be worked around... :-)

Ps. Keep up the fantastic work. my Nokia/Checkpoint combination is now in the
bin where it belongs.
