I  am  having  a  problem  setting a subnet mask for one of the networks
attached to my p4200.  The interface address is 128.173.1.1 and the mask
I am trying to set is 255.255.224.0.   I know that  this  is  a  strange
choice  of masks,  but three bits is all I can use at the moment without
changing a lot of IP addresses on the local cable.

>From IP Config,  I ADD SUB 128.173.0.0 255.255.224.0.   When I  re-start
the  router  (rel 8.1A),   it won't talk to anything on the local cable.
It doesn't even send RIP updates on the  local  cable.    If  I  use  an
eight-bit  subnet  mask,    the  router does send traffic onto the local
cable.

Proteon tech support says that this should work.   Can anyone  think  of
any other configuration item that I may be forgetting?  All of the hosts
on the local cable are in the range 128.173.[1-31].xxx.
