Another Routing problem
 

I've got this routing problem that I can't figure out.
And it's driving me crazy
I'm using RedHat Enterprise 3
main network
192.168.0.0



machine one (subnet router)
eth0 192.168.0.9
eth1 192.168.1.1

machine two
eth0 192.168.1.6



MACHINE ONE

ifconfig eth0 192.168.0.9 netmask 255.255.255.0 up
ifconfig eth1 192.168.1.1 netmask 255.255.255.0 up

route add -net 192.168.0.0 netmask 255.255.255.0 eth0
route add -net 192.168.1.0 netmask 255.255.255.0 eth1

route add default gw 192.168.0.9

netstat -rn
127.0.0.0 lo
192.168.1.0 0.0.0.0 255.255.255.0 eth1
192.168.0.0 0.0.0.0 255.255.255.0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 eth0
0.0.0.0 192.168.0.9 0.0.0.0 UG eth0


MACHINE TWO

ifconfig eth0 192.168.1.1 netmask 255.255.255.0 up

route add -net 192.168.1.0 netmask 255.255.255.0 eth0

route add default gw 192.168.1.1


netstat -rn
192.168.1.0 0.0.0.0 255.255.255.0 U eth0
127.0.0.0 0.0.0.0 255.0.0.0 U lo
0.0.0.0 192.168.1.1 255.255.255.0 UG eth0

This is my problem:

Machine Two can ping both ethernet cards on the machine one but cannot ping onto the 192.168.0.0 network
Machine One can ping machine Two and the other machines on 192.168.0.0

All have same netmask 255.255.255.0

I've got ip_forwarding turned on
I've got iptables turned off

I've also tried
on machine one
route add -net 192.168.1.0 netmask 255.255.255.0 gw 192.168.0.0 dev eth0

Am I missing something?

I'm starting to think it's not the routing but something else.

Sorry
 

Sorry,I tried to draw a visual that obviously didn't work out.
I'm not sure how do people use tabs or spaces to display the routing tables on this BBS?

answer
 

Just incase someone is crusing for answers to similar problems. I tried so many different routing configuations and a good explanation of routing is linked below.
But the answer to my problem was not there. The answer was: I COULD ping the network, it just couldn't ping me back. I thought that traceroute would show me what was going on but I was wrong. It was tcpdump -i ethx that showed me that the icmp packets were going through. So onward.
