From that Trusted Client List, I'm making the following assumptions:
xylose's IP is 192.168.1.51
fructose has two interfaces: 192.168.1.254 and 188.8.131.52.
xylose doesn't have access to your "live" 205.142 network and you intend for
all cluster traffic to be on the 192.168 network.
Verify that the first $clienthost in your mom config resolves to 192.168.1.254
with matching forward and reverse.
Also verify that the names in $PBSHOME/server_priv/nodes resolves to
192.168.1.51 with matching forward and reverse.
Either MOM is sending HELLOs to the wrong IP, the HELLOs are blocked in some
port filtering or firewalling, or server is sending INIT messages back to the
wrong place. My suspicion is the first possibility.
Crank the loglevels on mom and server all the way up to 9. MOM will log where
it is sending HELLOs, server will log who it got HELLOs from.
