Re: MSN helper module

["Carlos Fernandez Sanz" <cfs-netfilter@nisupu.com>]

Yes, it needs some support for file tranmission, voice, etc. The protocol
works a lot like FTP when using PORT (active) connections. The initiator
client sends its IP address and a port number for the other end to connect
to. For basic messaging it doesn't need any special NAT support, though -
the reason being that all connections are outgoing and there are no related
children connections.

So it is not a lot of work but it needs to be done. I haven't found anything
about it so I'm assuming no one has started any work, so I'll do it myself.
Anyway it's pretty much a one man job.
