Okay….
Seeing something different here.
My trouble IP 187 gives me this readout
$ route -n get xxx.187
route to: xxx.187
destination: xxx.184
mask: 255.255.255.252
interface: em1
flags: <up,done>recvpipe sendpipe ssthresh rtt,msec mtu weight expire
0 0 0 0 1500 1 0
when the good one that is routing correctly does this...
$ route -n get xxx.188
route to: xxx.188
destination: default
mask: default
gateway: xxx.185
interface: em1
flags: <up,gateway,done,static>recvpipe sendpipe ssthresh rtt,msec mtu weight expire
0 0 0 0 1500 1 0
Thank you for all your help</up,gateway,done,static></up,done>
