So, I don't follow this list, and don't know if anyone
has done this already, BUT,
the following patch to
linux/net/ipv4/ip_masq_raudio.c
should allow the same module to masquerade QT streamers.
This is based off the 2.2.10 kernel sources.
I'm not on any of these lists, so please direct queries
and responses to me in person if you care to have me
read them.
One concern. The qtss requires that the port
range start with an even port, and I couldn't figure
out how to get ip_masq_new to return an even port number,
so I just called it multiple times until it does.
If this will leak descriptors or if there is a
better way, please tell me.
Thanks
