Disclaimer:
===========
This software is provided as is. I take no responsibility if it destroys your
data or opens up a security hole on your firewall. That said, I have yet to
hear something about this happening.
I did not create this code myself, most was written by Tom Marshall, later on
Harald Welte and then Steven van Acker ported it to the new 2.6 netfilter API.
I just picked up this code in 2007 and made it compile and hopefully work with
the new changed netfilter API.
Bugs:
=====
Of course there are. One of the most important ones, is that you MUST NOT
filter outgoing connections otherwise the reply packes go missing. I tried to
figure out, why the _expect call is not taking care of the outgoing connections
but I was not able to figure this out. I gladly welcome patches that fix this
and other bugs.
Build Instructions:
===================
Have the kernel source ready in some place and NF_CONNTRACK_NAT enabled in the
configuration otherwise you will get an error during make. The Kbuild setup
looks in /lib/modules/\`uname -r\`/build for the source.
If the source is located in another place set the KERNELDIR environment
variable accordingly.
After that a:
* make
* make modules_install (as root)
should be enough.
Then do a "modprobe nf_nat_rtsp" as root and try to connect to a RTSP
service.
