Hello, I was wondering if the following could be done using the netfilter hooks :- I want to process incoming packets to one of my addresses
and my ports to be forwarded to some other destination ..
the complication arises due to the fact that the destination will be determined
dynamically i.e based on the port on which the packet
arrived, I need to communicate with some other machine using udp and determine the destination to which this is to be
forwarded, this destination also needs to be cached so that any future packets
on this port can directly be sent to the destination… I was doing it in
user space using divert sockets but efficiency is a key concern and so was
thinking about in-kernel processing …I presume I need to write a kernel
module and hook it to netfilter … or am I totally
on the wrong track .. if yes, then I was concerned
about the fact that I have to contact some other machine to decide whom to
forward this packet too! Thanks, Hitesh |
