Please note this is an experimental module. It works for me. It may work
for you, it may panic your kernel, or it may just sit there using ram.
Features:
* Detects STUN and stays out of the way.
* Understands proposed client_port=M/N syntax.
* There is a configurable policy for the destination parameter.
TODO:
* Handle multiple SETUP messages in a single packet.
* Un-mangle client_port on return trip.
* IPv6 modules
* Much more...
This should work with 2.4.20 and all of 2.4.21-pre# series up to and
including pre7, at least. It should not work with 2.4.19 or prior. I am
making _no_ attempt to do p-o-m or non-kernel iptables support. Others may
feel free if they wish (hey, it's GPL).
The diff was prepared against 2.4.21-pre6. Please use the "-p1" option to
patch(1) for proper application:
# cd linux-2.4.21-pre7
# cat ../nf-rtsp.diff | patch -p1
Comments (especially bug reports and success reports) welcome.
Hints about IPv6 conntrack and nat modules very appreciated (why is there no
IRC or FTP modules for IPv6?)
