Hello,

Sunday the 23d of June we renumbered all our IP-addresses on our network, 
because we have now an class B internet address. We use subnet mask 
255.255.252.0.
For (subnet)routing we use the cisco AGS+.

We have a problem with clients and yellow pages servers which are not
on the same subnet. When PC-NFS is started on the PC, the server
doesn't answer and no connection is made. The PC-NFS guide says:
"If both yellow pages and reverse ARP (RARP) are used, the Yellow Pages
server used during the netstart RDR process MUST be on the same subnet
as the PC". 
We tried to solve this problem with the configuring of a helper address
in the cisco-router, so UDP broadcasts are forwarded. It didn't work.
 
The AGS+ has been connected on ethernet with one ethernet interface. 
We use secundary addresses for subnetting. Between the ethernet segments
we use bridges. 

Does anyone have experience with Yellow Pages servers and clients which are 
not on the same subnet ? Or is it really necesary to put both client and 
server on the same subnet ?

Thanks in advance,
