Ok. A few things.
1) The IP numbers you are using, were those assigned by your ISP
or did you make them up? I would think that if you got assigned
numbers, your ISP would give you 2 contiguous ones.
2) The Netmask seems wrong. I have my own block of IP's for my
home use (free from my ISP), and I have a net mask of
255.255.255.248 ( I have a block of 8 IP's and thats all I see
with the netmask).
3) You also need to tell NT that it is to route packets for your
network. You didn't indicate you made the registry change to
allow this. If you don't then I think the packets from your
local machine would just die (everything would get routed through
the modem to lala land).
Check out
http://www.sturtevant.com/technote/RouteNT.html
It tells you how to setup your NT box as a router for a small LAN
(no extra software needed if you have individual IP's, or you
need a proxy server).
Does this help you out ?
