I tried to send this once and gmail gave some error so I hope you
don't see this twice.


I'm using a Pentium II with NetBSD 3.0 to connect to the
Internet with a modem and ppp and I have a computer running
Windows XP that is connected to the computer that is running
NetBSD with ethernet. The NetBSD box is 192.168.0.1 on the
ethernet and the Win XP is 192.168.0.2

I Have been trying to use nat to allow them both to access
the internet at the same time but If I reboot the NetBSD computer
or redial sometimes I can get the nat to work.

when I use map ppp0 is there something I need to do so that
when the address for ppp0 changes the nat will keep working?


Here are my setup files.
