	Hello:
	I'm studying the Netfilter architecture, and I have read the
"Linux netfilter Hacking HOWTO", but I have some problems to understand
many things about it talks about, so I would like to know if there is
another document explaining Netfilter architecture, or if it doesn't
exists, where I can find some help (maybe a Linux kernel book or
something similar) to understand all the concepts.

	Thank you very much


	Juan

Hi,
Was reading your writeup about the netfilter architecture 
http://www.netfilter.org/documentation/HOWTO//netfilter-hacking-HOWTO.ht
ml
 
I was not able to figure out whether all this functionality is done in
the context of a single ISR for each IP Packet or is the traffic cached
and opperated on in the back ground?
 
Wondering if you could provide me links and potential issues/
performance guidlines if you are operating in the context of an ISR.
 
thanks,
 
aditya
