1. Network hanging - Tulip driver with Netgear (Lite-On) NIC

2. I am trying to prepare a new firewall host with a Pentium III and
three Netgear NICs and am experiencing considerable trouble with the
combination:

Kernel 2.4.[01]: ifconfig shows that the card see's traffic on the
network, but does not transmit anything (no response to ping).

Kernel 2.2.16: appears to work, but only for a short while. In
particular, running IPTRAF, with the card in promiscuous mode, will work
for 2 - 5 minutes, then the card will hang. The ONLY recovery that I have
found is too reboot the machine.

Using the kernel 2.2.16, I have tried various combinations:
· I have removed all but one of the NICs; no change.
· I have changed the version of the tulip driver: I have tried
0.89H, 0.91g, and 0.91g-ppc with similar results on all drivers.

3. Keywords: modules, networking, tulip drivers

4. Kernel Version : 2.2.16 / 2.4.1

5. .

6. Environment:

Hardware : ASUS P3W-E motherboard; Netgear FA310DX (LC82C169C) NIC

7. I am currently running a similar configuration on an older Pentium
166 MHz, with three Netgear cards, as my present firewall host - Linux
2.2.16 + ipchains, and experience no problems with this combination.

I am at a total loss as to what steps to try next. Any advice / comments
would be appreciated.
