ip_forwarding / gateway



Hello,

I am building a network of Linux boxes running a small self-made Linux. One
of these boxes is setup as a dial-in server for the network. I have the
dial-in part up and running, but have difficulties configuring the network
such that I can reach the Linux boxes from out of the network.

This is my setup:

92.168.2.1 <---ppp---> 192.168.2.2 <---ip_forwarding on the dial-in
server---> 192.168.5.1 <--- eth ---> 192.168.5.2 <--- eth ---> 192.168.5.3
etc.

My dial-in server has ip address 192.168.2.2 on the ppp connection and
192.168.5.1 on the eth connection. 192.168.5.x is the Linux network.
Ip_forwarding is turned on the dial-in server.

Using the pc with IP address 192.168.2.1, I am able to ping the Linux
dial-in server on both its IP addresses (192.168.2.2 and 192.168.5.1).
However, I cannot reach the Linux boxes with IP addresses 192.168.5.2 and
up. When I ping these boxes, I can see the lights of the Ethernet cards
flicker, but the ping requests time out.

Am I overlooking something? Any help is greatly appreciated.

Regards,
Whinyan.
