I have a small linux-router with 3 nics builtin (eth2 has been built-in additionally 2 days before):

my routing table looks as follows:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 eth2
192.168.0.0 * 255.255.255.0 U 0 0 0 eth1
10.0.0.0 * 255.0.0.0 U 0 0 0 eth0
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth1
from this machine, i get without any problems in net 192.168.0.0 and 192.168.2.0 and 10.0.0.0. But: I cannot get from 10.0.0.0 to the others (except if i am on the routing machine.
I set /proc/sys/net/ipv4/ip_forward to 1, so routing should be working fine. But somehow it doesn't. My firewall is deactivated for the moment.
Traceroute from 10.0.0.1 to 10.0.0.2 is even not working (* * *). Ping -b 10.0.0.0 from 10.0.0.1 even doesn't show up 10.0.0.2....
Are you sure the client 10.0.0.1 is configured with:
IP = 10.0.0.1 Netmask = 255.0.0.0 Broadcast = 10.255.255.255 Gateway = 10.0.0.2
