Or just set your Linux system as a bridge.
| What is happening is all these IP addresses are on the same subnet (using
| 255.255.255.0 mask i bet). The machine (pick any one) wants to send a packet,
| it sees the destination is on the same subnet, so it will arp. Since the
| destination is on another wire (unles it's dest is the Linux box), the arp
| fails. The only communication is with the central linux box.
Because the Linux system is not being a bridge and providing the ARP.
| Now for a better way. Use subnetting. Keeping the 255.255.255.0 mask...
| Linux Box, 220.127.116.11
| Linux Box ppp0 18.104.22.168
| Linux Box ppp1 22.214.171.124
| Amiga 1 ppp interface 126.96.36.199, gateway 188.8.131.52
| Amiga 2 ppp interface 184.108.40.206, gateway 220.127.116.11
| Win95 18.104.22.168, gateway 22.214.171.124
This requires each system to know about routing. While it certainly
works, from a standpoint of configuration, if it were my system I would
use bridging and convince all the machines that they were on the same
And you omitted having each machine set the Linux machine as the default
route to the world.
As a general rule, routing is desirable when you only want certain
packets to pass between physical rings, and bridging is desirable when
you want to pretend all systems are on the same ring.
