OpenBSD 5.0 PF and Syn attak

[Pui Edylie]

Hi Everyone,

I am trying to put a pair of OBSD box together to provide Syn, UDP and 
ICMP flood protection with pretty graphs.

May I know if anyone has accomplished this?

If you had, I have the following question

1. What is the hardware spec you use? What is the maximum attack PPS and 
Bandwidth were you able to absorb?
2. What do you use for graphing?

Thank you for your time :)
