As Tariq Rashid already explained, natd does not store the information
inside the kernel. Several of my machines use NAT via ppp(8)'s built-in
interface to libalias (which is functionally pretty much the same
as natd(8)), and several months ago I wrote up a quick hack to libalias
and ppp(8) to display the list of currently masqueraded connections.
However, it turned out to be not all that useful, since there were some
issues with timing out connections, so I kind of let it rot.
If there is enough interest, I could resurrect it and post it for review
and suggestions for improvement.
G'luck,
Peter
