[Asterisk-Users] OT: Linux routing with T100P problems

[Matthew Boehm]

Hey gang,
 I was successful in recompiling my 2.4.20 kernel to support HDLC. I was
successful in hooking up our T1 line into the zap card. I was successful in
being able to ping equipment on the other end of the T1. I was unsuccessful
in pinging the outside world from the other end of the T1.

I've attached a cheezy image of the network. Here is the routing table:

[root at asterisk root]# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
10.0.5.2           *             255.255.255.255 UH    0         0        0
hdlc0
10.0.0.0           *               255.255.255.0   U       0         0
0    eth1
10.0.3.0           *               255.255.255.0   U       0         0
0    eth1
65.78.109.0     *               255.255.255.0   U       0         0        0
eth0
127.0.0.0         *               255.0.0.0           U       0         0
0    lo
default       65.78.109.2     0.0.0.0               UG    0         0
0    eth0

There are 2 NICs (10.0.3.10, 65.78.109.10) and 1 T100P (10.0.5.1) on this
box.

Like I said above, from this machine I can ping everything in every attached
network and the outside world. For some reason, I cannot ping the outside
world if I am comming from the 10.0.0.* network on the diagram. From that
network, I can ping 10.0.5.1 (this box) but nothing else.

I'm a little stumped. My iptables are completly empty. If this is waaayyy
off topic, please contact me off list. But I figured since it was related to
the T100P it might be relevant.

What can I use to find out why packets destined for the outside world (via
65.78.109.2) are not being routed?

Thanks,
Matthew
