Linux packet capture to act before iptables or...

I need a linux packet capturing software to act in 2 possible ways (you choose the best solution):

1) It act BEFORE iptables, so, an algorithm will analyze the packet info and, depending on algorithm result, it will to run a command on system, like "iptables -I INPUT -s IP_FROM_PACKET -p udp -j ACCEPT"


2) It act AFTER iptables, so, an algorithm will analyze the packet info and depending on algorithm result it will allow or block the packet to go to main aplication

why do I need that?

I'm receiving a spoofed udp attack, so I want to make an automatic whitelist.

one possible way is to have all possible ipv4 on a list (I know, I would need something like 40 GB RAM, but I don't care if it works well)
