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:
Do you know the STRING module ?
I'm afraid not. Can you give me some explanation (or link)?
Is it possible to obtain some address info (source/destination address
and ports) from the packet queued from netfilter?
