Problems Setting up RedHat 9 Box as Router

[midraga]

Hi all,

I have a LAN of several linux computers they are all able to communicate
to each other on the LAN, however the computers on the LAN can't contact any
host on the Internet - (only my RedHat 9 gateway box is able to contact the hosts on the
Internet through its ppp0 interface)

Configuration details:
computers on th LAN:

IP Role Gateway
192.168.0.4 Client 192.168.0.5
192.168.0.5 Gateway acc2.bur.connec 0.0.0.0 (temporary for ppp0)

the output of iptables -L option on my gateway is:

Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere

Chain OUTPUT (policy ACCEPT)
target prot opt source destination


On the gateay I did: "echo 1 > /proc/sys/net/ipv4/ip_forward" to enable
forwarding

When i try to ping a host on the Internet (131.170.40.30) from 192.168.0.4 and
I run the ethereal or my ppp0 interface on 192.168.0.5, I get following output:

1 0.000000 192.168.0.4 131.170.40.30 ICMP Echo (ping) request
2 1.013459 192.168.0.4 131.170.40.30 ICMP Echo (ping) request
.
.
and so on

why i don't get any replies from the Internet.

Thank you for your help
