It sounds like your problem could be solved with a conntrack helper 
application, similar to the ones designed for IRC and FTP connections. A 
quick search on Google didn't reveal anything useful, though I suspect 
someone has already taken the time to write one. The netfilter website would 
likely be a good place to start looking for that add-in.
