Subject: netfilter_queue: how to obtain address info from queued packet
Date: Tue, 23 Jan 2007 11:03:44 +0100	[thread overview]
Message-ID: <45B5DD80.70809@siemens.com> (raw)

Hello all,

I am quite a newbie to the netfilter world, so maybe my approach is 
naive. I would like to block communication coming from/to some ports 
according to the content of packets. Unfortunately these ports are not 
static, so port specific netfilter rule cannot be used. So my question is:

Is it possible to obtain some address info (source/destination address 
and ports) from the packet queued from netfilter?


Thanks in advance for any help,

Michal
