Help,
 
I am attempting to help one of our researchers here at O.U. get his TCP-IP
software working on his RISC 6000 computer (running AIX). We have been using
the SMIT program to do the configuration. I have set the minimum parameters
such as address, host name, interface, and netmask to values that are
appropriate.
 
Now comes the problem, when I try to ping or otherwise communicate with
another tcpip address I get nothing (ie. ping send packets but receives 
none back). If, however, we attach a PC with an ethernet adapter on the
same segment of the network the Risc 6000 can sucessfully communicate
with this PC and this PC can communicate with the Risc 6000. Also, other
known working tcp-ip devices on other segments of our network can 
communicate with the RISC 6000.
 
A simplified diagram is below:
 


       PC1>----|
               |
               |
RISC 6000>-----|
               |
               \
                \--dempr--lanbridge 150---|
                                          |
                                          |
                                          |---bridge--dempr--PC2
 

So,  RISC 6000 sees PC1
     PC1 sees RISC 6000
     PC1 sees the world (ie. PC2)
     PC2 sees the world (including RISC 6000 and PC1)
 
Needless to say I think this is a simple problem but alas the Docs for
the AIX/TCP-IP are non-existant. If you have gone through this and might
be able to help send me email or call me on the phone or send me email and
i'll call you on the phone.

Any and All help will be greatly appreciated!
 
thanks.....
