can't forward

[Michael West <web@mitzit.net>]

I am setting up a new gateway and it will not forward.

The gateway looks like:

eth0 10.0.0.2

eth1 10.0.1.1

eth2 10.0.2.1

---------------------

route:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
10.0.0.0        *               255.255.255.0   U     0      0        0 eth0
localnet        *               255.255.255.0   U     0      0        0 eth1
10.0.2.0        *               255.255.255.0   U     0      0        0 eth2
default         10.0.0.1        0.0.0.0         UG    0      0        0 eth0

---------------------

cat /proc/sys/net/ipv4/ip_forward

1

---------------------

iptables -L

Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

---------------------

I cannot ping from 10.0.2.2 through the gateway to 10.0.0.1

The gateway can ping both 10.0.2.2 and 10.0.0.1

from 10.0.2.2 a traceroute 10.0.0.1 shows that the packets are routed to
the correct gateway interface 10.0.2.1 but that is a far as they get.

What is the next step in diagnosing the problem.  Did I forget something
silly?
