Subject: Cant get 3.11 IP router to PING

The Novell gurus here have asked my help with our first attempt at IP routing
thru 3.11 servers.  The application is a few macintoshes which will run
NCSA TELNET to get to our VAX.

                        ser0
                         +--->to WestNet
     VAX             CISCO                 NOVELL                MAC
      +--------------+   +-----------------+    +-----------------+
      VAX net        e   e  campus backbone       media lab net
      IP 192.80.27.0 t   t  IP 161.28.1.0         IP 161.28.64.0
      IPX C0501B00   h   h  IPX A11C0100          IPX A11C4000
                     1   0
                     
192.80.27.1    192.80.27.126                  161.28.64.254
Netware VMS           161.28.1.254      161.28.1.64            161.28.64.100
& Multinet           8.2(7)                 3.11

PC's sitting beside the Mac can see the VAX on SLIST.

I read the FM and set eveything up as (I think) it says.
Both the VAX net and the campus backbone are set for Ethernet II packet types.
TCPCON sees packets arriving every few seconds.
The cisco ARP cache has a correct entry for 161.28.1.64 .
BUT -- no traffic flow.  The cisco can't even get a "ping" echo from the
server.

This one says: Load tcpip forward=Yes rip=Yes

Done.  Mac says gateway is 161.28.64.254

Cisco is set "route rip"

OK there subnets and masks are set on both Novell interfaces

Still the server will not answer a PING.

So:
Q1:  Is a healthy 3.11 IP router supposed to PING?

Q2:  If so, what can stop it?

Q3:  (more advanced)  Do I need to worry about re-distributing the RIP
derived routing info out to westnet?
