I'm setting up a gateway box with potato on a scavenged P75 box with one newer
Intel EtherExpress 10/100 PCI NIC (eth0) and two older Intel EtherExpress PRO/10
ISA NICs (eth1 and eth2). Target topology is a DMZ network and an internal
network, both masqueraded to the outside.
However, I've got problems with the two ISA NICs. I configured them with
isapnptools, and they show up ok in ifconfig. I can ping them from the keyboard
of the gateway box. When hooked to their hubs, their connection LEDs come on,
and their activity LEDs flash as network traffic goes by. So far so good.
But I can't ping either of them from other boxes on their networks. I haven't
implemented any type of firewall yet; I'm just trying to connect. The question
is whether there is something wrong with the NICs or if it's something I haven't
configured right (OK, I admit it--I'm a relative newbie here).
During boot (shown in dmesg), the two NICs report "multicast setup failed", and
when I ifconfig them from the command line, I see this also. Nevertheless,
ifconfig reports them UP RUNNING MULTICAST. Any idea what this discrepency
means? I've
posted this question to an Intel forum to ask whether this is a hardware
problem. Or is there some stupid configuration error I'm making here?
*Many* TIA for any ideas. Following is more detail:
