Yeah, I use it too.

Such as using 10.0.0.0/8 and using NAT! =( Thanks to a few of the internet
providers that use MxStream to do ADSL that has been pushed out. (To show
you how messed up KPN is at times)

OK so I'm not the only one experiencing this from time to time.
I have not seen any bufferspace messages however, am I correct that you
don't get that anymore since switching to natd?
I haven't had too much time to find out what's going on, but from time to
time my connection seems to freeze up, and indeed when I look in top, natd
is eating a large chunk of the CPU time. But when I look in trafshow I see
something very strange. One connection has an enormous outbound rate. It
would be trying to push a few megabytes per second down the 256Kbit
upstream that I have (for other MxStream users, yes I have the Fast variant
and I'm loving it!). There must be some sort of loop somewhere that's
resending the same packet over and over again, as a lot of the times my
windows box will be the one responsible for the connection and it's not
pumping that data over my internal LAN.
Any natd/mpd/netgraph guru's have any hints about where to start
looking/how to debug this? If I'm not the only one having this problem I'd
like to get this out of the way ASAP.
