Patrick,
A couple of "brute force" things to try:
1. Check for link from the hub to the mail server. I assume this is
good since you can ping the outside interface of the GW. I don't see
any way that traffic could get from the mail server to the GW without
going through outside the hub. No routing on the 10.1.0.0 network.
2. Verify routing with traceroute. Try traceroute 206.58.200.33 from
the mail server. Then try traceroute to an internet IP address. That
should tell you how far the packets are getting.
Just out of curiosity what is upstream of the hub (your CPE)? To
clarify one other thing for me. Is there a hub connecting the boxes
together on the 10.1.0.0 subnet as well?
I don't see anything wrong with your config.
Bob...
1. There should not be any because the GW for the mail server is the
ISP GW of 206.58.200.1
2. Here is the TraceRoutes of the Mail to and GW systems.
This is to the GW system not the ISP gateway. The GW system is attached
to the hub that the Mail system:
[mail ~]$ traceroute -v 206.58.200.33
traceroute to 206.58.200.33 (206.58.200.33), 30 hops max, 38 byte packets
1 206.58.200.33 (206.58.200.33) 46 bytes to 206.58.200.39 7.806 ms
0.459 ms 0.442 ms
This is to the ISPs GW which can be pinged by the GW system but not the
Mail system:
[mail ~]$ traceroute 206.58.200.1
traceroute to 206.58.200.1 (206.58.200.1), 30 hops max, 38 byte packets
1 206.58.200.39 (206.58.200.39) 3000.343 ms !H 3000.381 ms !H
3000.118 ms !H
3. Here is the topology:
ISP GW (206.58.200.1)
|
WIFI Modem (ISP Modem of which there is one Ethernet Connection, have no
access to its config, think it acts as a bridge)
|
My External Hub
| |
GW System Mail System
| |
My Internal Hub
|
Internal Network
I am almost completely convinced that there is a routing problem at the
ISP. What do you thing?
