Robb,

Thanks for the info.  Unfortunately, none of these options is very suitable
(see below).

We are planning to modify the ldm.h and ldm.x file to add the feedtype, so
that we can restrict data from the feeder machines.

I do not have control over the outside machines.  We are trying to restrict
the outside machines from getting the data from the feeder machine.  The
request statement would be on the outside machine side -- not on the feeder
side.

Unfortunately, allow only restricts by free type -- not with a pattern.
I need more than two feed types ... like 3 - 5.
