[Sunhelp] sunPCi question

[Frank Sommers]

Hello, 

I finally bought a SunPCi card for my Ultra 5 which allows Win98 to be
used from within the same box. It installed fine, however, Solaris and
Win98 cannot talk to each other. According to the documentation, the
communication is arranged via TCP/IP. The two systems share the same
Ethernet card, and the only way for them to communicate is via a 3rd
device, e.g., a router. So I set up my old Solaris 2.6 x86 box as a
router. Now I have the following problem:

Suppose the Ultra 5 Solaris system is assigned IP address A, the Sun PC
co-processor card (Win98) is assigned IP address B, and the x86 Solaris
box (with its own Ethernet card) is assigned IP address C. I added these
routes:

to A: route add B C 1
to B: route add A C 1
to C: route add A C 0
      route add B C 0

In addition, I enabled IP forwarding on the x86 box:
ndd -set /dev/ip ip_forwarding 1

Now, I can ping C from both A and B, but I cannot ping either A from C or
vica versa. Clearly the x86 box is not forwarding the packets through.
What am I doing wrong? Has anyone on the list any experience with the
SunPCi card?

Any suggestions would be welcome.

Thanks,

Frank Sommers
