Subject: Get ip before accept

Hi
I'm trying to get a client ip before calling accept
Any ideas how?
It should be possible to get ip from connection queue when switching to
kernel space should it?
If ip doesnt't match a given list i want to close the not fully established
connection

Cheers,
Stephan

Try netfilter/iptables:
