Hello,

I had problem in configuring the IPNAT to work. I follow the steps to
setup the IPNAT and could not make it work.

1. I test the LAN is ok as I can ping the gateway (dialup line to ISP).
2. I ping other host in the internet without any messages back except the
ip address of it.

Anyone can help ? Here is the setting of my system for the IPNAT. My system
is netbsd-current (jun 30, 1999)
