ipnat has stopped working reliably for me.  I'm not sure what build this 
started happening as it almost works so has taken a long while to realise that 
there is a problem. It was before build 60 and is still an issue in 64.

The problem appears to be that if a connection is idol for more than 3 seconds 
then ipnat forgets about the connection and drops it. It will bring it back to 
life if the next packet comes from inside the nat configured connection but not 
if the next packet is from the outside.

So this simple ssh script is o.k.

while sleep 4; do echo x ; done |ssh remote.host.com 'while :; do read x ; read 
x ;ec
ho x ; done'

But this one fails:

ssh remote.host.com 'while sleep 4; do echo x ; done'    

ipnat does not show a connection and snoop shows the data is coming back and 
been accepted by the nat router but not forwarded back to the system from which 
the ssh was originated.

Any ideas?
