The default route is 10.10.10.4 (Firewall 1)

> - Firewall 1

10.0.5.4/30 eth1
10.0.5.8/30 eth1
10.0.1.0/24 eth1
10.10.10.0/24 eth0

> - 10.0.5.10

Gateway of last resort is 10.0.5.9 to network 0.0.0.0

     10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks
C       10.0.5.8/30 is directly connected, Serial0.1
S       10.10.10.0/24 is directly connected, Ethernet0
                      is directly connected
S       10.0.1.0/24 [1/0] via 10.0.5.9
C       10.0.5.4/30 is directly connected, Ethernet0
S*   0.0.0.0/0 [1/0] via 10.0.5.9

Items below this should be out of the picture, as the packet drops are
between 10.0.5.10 and firewall 1.

I put a logging on the ipchains for eth1 input, output and forward, and on
eth0 forward.

I noticed that the ping packets follow the following chains:

eth1 forward
eth1 output

eth1 input
eth0 forward

On the packets that are dropped, they don't appear on the eth1 input chain
log however I do see a flash on the tx packet light on the router.
