I was trying to set up a debian box as a gateway from a small 4-bit subnet to a larger 8-bit (class C?) subnet. I have the kernel configured properly (I think), and I have the two network interfaces on the gateway and the routes set up.
>From one of the machines on the 4-bit subnet I can ping all the other machines there, and the gateway machine, including both of the gateway's interface addresses, the one on the subnet, and the one on the external net. However, I can't ping any other machines on the external net. I have used tcpdump on the gateway machine to see that the pings are going out, but that the higher level gateway on the external net is sending arp lookup packets for the machines on our 4-bit net, and getting no response. Our administrators said that our gateway machine should be responding to these arp packets for all the machines on our 4-bit subnet, but it's not. Can someone how I can make this happen?
