Uhm....Unless all the PCs are connected to the same switch, as is all the 
interfaces of the Juniper, this setup will just not work.  The PCs will all 
believe that they're local to eachother and on the same LAN segment, if 
they're not they won't find eachother via ARP.  Not sure what your'e trying 
to accomplish by having four interfaces in the same subnet, but I doubt 
it's what you want.
