A network client can't ping a foreign host via a ppp connection

I have two computers (both running linux) in a network. One of them (slackware) connects to the internet via ppp. The other (red hat) cannot ping an outside host.

The result of route on the client (red hat)

Destination Gateway Genmask Flags Metric Ref Use Iface * U 0 0 0 eth0 * U 0 0 0 eth0 * U 0 0 0 lo

default UG 0 0 0 eth0

The result of route on the server (slackware)

Destination Gateway Genmask Flags Metric Ref Use Iface * UH 0 0 0 ppp0 * U 0 0 0 eth0 * U 0 0 0 eth0

loopback * U 0 0 0 lo

default UG 0 0 0 ppp0

Thank you!

The Slackware machine needs a few other settings to make it a gateway, namely ip packet forwarding and ip masquerading.

See the masquerading HOWTO for details...
