You will have to use a tighter netmask than what you are using, your example
above would make both interfaces thing that they are in the same subnet.
That could account for the errors as both cards would think there were on
the same ethernet segment.
Also as a diagnostic try typing routed -s at the command line and it will
give you an error if i/p forwarding is not on. Make sure you
first kill any copies of routed that are already running.
Try 255.255.255.248 for your netmask, that will give you
eight address in each subnet (6+network+broadcast).
