We have an ethernet LAN in our laboratory consisting of 5 masscomps, 1 DEC
LSI 11/23, and several PCs.  We would like to connect our LAN to 
a similar but larger ethernet LAN at our institution (also running TCP/IP).
We will need some kind of ethernet bridge or gateway in order to do this, and
we would like to use one of our masscomps--a PEPed 5500--as this bridge or 
gateway by running two ethernets from the same machine.  My questions are as 
follows:

1.  Our local sales rep (who is next to worthless on technical questions)
    says that masscomp has software called "Dual Net" that will do this 
    and allow us to run two ethernet boards in the same machine.  Has
    anyone out there heard of this software or had any experience with it?
    Better yet, has anyone tried to do what we are attempting?  If so, how
    did you do it?

2.  As part of our PEP package we got a Lance chip on the MPU motherboard.
    We also have a 201 board on this machine, which we are currently using 
    for our ethernet.  Does anyone know whether we can use the Lance chip as
    our second ethernet or do we need to get another 201 board for this 
    machine?

Any help on this would be much appreciated.
