[comp.protocols.tcp-ip] Help on Sun routing

N39@applelink.apple.com (04/21/89)

Help!

I am sending this message on the advice of Chris Vandenberg from ACC
(chris@SALT.ACC.COM).  He says somewhere someone will have the answer.  I hope
so.  We (Deere) don't have our DDN connection yet.  Consequently I'm sending
this from my AppleLink mail address on Apple's 4381 through a mail gateway to
the Internet.  (Hey, what-ever works!)  Replies can be sent to Doug Foster,
Deere & Company (n39@applink.apple.com).  See below.

The problem:

We have an IBM 3090 running MVS and ACC's ACCES/MVS product (v2.1.1).  I am
building a Deere wide-area internet.  Because of design considerations, we are
implementing some short term solutions (they always start out short term don't
they?).  Anyway, the 3090 (192.43.1.1) is using a Sun 3/140 (192.43.1.3) disked
machine to gateway for him.  The Sun is running Sun OS 4.0.1, pretty much
generic kernal.  The Sun has routes to networks 192.43.3, 192.43.4, 192.43.13,
etc..  These routes were added with the "route" command & set at 0 hops, since
the different logical nets lay on the same physical net.  Problem is ACCES/MVS
arp request/replies are OK, forwards to the Sun gateway are OK, but the Sun
will not route!  The Sun has one interface (remember multiple logical nets on
the same physical net), has IPFORWARD on in /usr/sys/netinet/ip_var.h.  I even
tried the "adb -w /vmunix;ipforward? w 1; cntrl d" business, no diff.  If I
switch to a stock Sun 3/160 running Sun OS 3.4, it works!  What's the diff?  I
need to get this resolved pronto.  Managers & time schedules, you know. Any
help????

Thanks,
