Hello All,

I have some problems connecting two computers with ppp.
One computer is connected to the ethernet line and has
a modem. I want to route traffic through this one.
I connect from the second computer using iij-ppp 
and everything goes fine, i.e. when I start ppp -direct
on the first computer or pppd I can connect to it 
but traceroute stops on it and doesn't go furhter.
The routing tables on both computers seem to be OK.
The first computer:

On the second computer (client):

I have compiled the kernel on the first (server) computer with
optinons GATEWAY
and use:
sysctl -w net.inet.ip.forwarding=1
in /etc/netstart.

Any suggestions,
Any help will be highly appreciated.
