BM 3.7 patched to 3.7 FP3D, I think, Netware 5.1SP6.
(I can patch it up to 37FP4A and new IP stack, but, read the message)

Our BM 3.7 box, about 2 months ago, started occasionally doing this:

Out of the blue, the public NIC (which is crossovered to the internet
router) will stop communicating with that router.

All internal comms are fine (private NIC). NOT a filtering problem, as you
can unload IPFLT and it continues. I can ping the bound public IP, I can
ping loopback, but I cannot ping the internet router.

I have replaced the public NIC with a known working one.

The only solution to the problem is to reboot the server. The server may do
this twice in a day, and then it may not do it again for 2 or 3 weeks. You
just never know.

Any ideas?
