Need to see if the following scenerio is possible and if so, how is it
achieved.

Scenerio XYZ

        We had a private FDDI backbone.  This was used to pass large flat files
for database loads and and as a backup path for certain machines.  This
network was a 10 node private network with no connection to the
internet.

        We now have another machine in a remote location.  For security and
performance purposes, we still wish to pass these same files to this new
node via the FDDI network.  However the FDDI is now connected to the
internet.  Because of the limited number of nodes available to the FDDI
network, our Network operating center split the Class B subnet of
128.ccc.ddd into two smaller subnets.  The FDDI uses the second subnet.
We also associated the new IP addresses with names in the campus name
servers.  We now have a problem with one machine have two ways to get
the internet, and thus to our new node.  We do not want to change the
default subnet for our boxes(128.aaa.bbb.0) but we want any
tranfers/communications to/from the new node to occur over the FDDI
connection.

        We have configured our networking on the Unix and MVS systems to
achieve this but cannot figure out if and how this can be done on an
HP3000/iX using MPE5.5.  We do not want to turn the HP into a router, we
just want two communication paths, one for systems on the
128.ccc.ddd.128 subnet and one for the 128.aaa.bbb.0 subnet.  We also
want all communications with 128.ccc.dd.eee to take place on the FDDI
connection, which is not on either subnet.

        Can this be done?  If so, how?  We are in a crunch to complete this
task so we do not have to transfers large files first to a UNIX box over
a 10BaseT connection then again over a FDDI connection to the new node.
