[Spread-users] Configuration Matters - Network Topology

Let's say that I have two networks:
192.168.0.0/24
10. 0.0.0/24
(and I have 1 or more machines in each network running Spread, and
there's at least one machine in this configuration that has two network
cards and consequently bridges the 192 and 10 network - let's call this
machine the BRIDGE).
Now, let's say I have:
192.168.1.1 (part of a 192.168.1.0/24 network)
...which also runs Spread and can route packets through to the
10.0.0.0/24 network [but has no direct access to the 192.168.0.0/24
network].
What I want to do is have a Spread daemon running locally on
192.168.1.1, which will then talk to the machines on the 10.0.0.0/24
network which then talks to the machines on 192.168.0.0/24 network.
To put this another way, how do I setup a segment so that the Spread
Daemon on 192.168.1.1 *knows* about the BRIDGE and/or any of the other
machines it has a route to but is not part of their network?
Currently I've tried:
# This is equiv. to 192.168.1.1
Spread_Segment 219.90.130.255 {
localhost 219.90.130.138
}
# This is the 10.0.0.0 network
Spread_Segment 203.2.124.63 {
nf3 203.2.124.30
}
Here's what Spread logs:

[Thu 03 May 2007 04:27:54] Configuration at localhost is:
[Thu 03 May 2007 04:27:54] Num Segments 2
[Thu 03 May 2007 04:27:54] 1 219.90.130.255 4803
[Thu 03 May 2007 04:27:54] localhost
219.90.130.138
[Thu 03 May 2007 04:27:54] 0 203.2.124.63 4803
[Thu 03 May 2007 04:27:54] ====================
There is a Spread daemon on nf3 configured with the same configuration
except I start taht daemone with a -n nf3.
Both these Spread daemons were built from the Spread-4.0 source tar
balls but one is on an Ubuntu GNU/Linux (the first one called localhost)
and the other one is a FreeBSD 6.2 (called NF3).
Needless to say, "localhost" messages/joins etc don't get sent to the
Spread daemon on "NF3" (as I can't see them with spuser).
As is probably noticable, I'm a little fuzzy as to how to describe the
problem I'm having...
