Setting up an OpenBSD firewall... Got OBSD installed, can't see both nics!

I did an FTP install of OpenBSD (surprisingly painless) and got everything up and running... I plan on turning this box into a firewall, so that only one of the nics wrorking does me absolutley no good!...

The PCI nic works fine... however, the ISA nic (Etherlink 3 509B) refuses to be recognized... it does not show up in the ifconfig -a list (even though it is supposedly supported)...

any ideas on how to troubleshoot this? this is my first playing with a BSD, so i really hope it cooperates...

One thing that it could be: the hardware page recommends that i turn off pnp for the card... is that a bios setting or something? im at a loss!

thanks for the replies...

(id post a link to the hardware support page, but the forum won't let me... sorry!)

Yes, pnp support is a bios setting. Turn it off. Then see if the card is recognized.

If not, try disabling the card (or onboard) that *is* recognized and see if that helps.

Remember, the cards really want to be on different subnets to function. *AND* you'll have to turn on IP forwarding so packets are routed from one interface to the other.

I was trying to use Etherlink III myself just last week. OpenBSD had a hard time with it and when I tried to use it with PF it just wouldn't work. I went and got a PCI 3c509 card and everything worked like a champ.

I would recommend simply getting a supported PCI NIC. It will probably end up being less trouble in the end. You can get some great deals on-line if you're willing to wait (I got a whole bunch of Intel 82559 cards for $13 each) or you can head down to Fry's, Microcenter, CompUSA, etc and try to find something there (although they'll overcharge and probably won't have the really good cards--Intel). For instance, I recently had a Netgear card go bad on me and I had to buy a replacement for two days until my Intel cards arrived by FedEx. I picked up a Belkin card at Microcenter for $9 after mail-in rebate (not sure if Belkin is supported by OBSD, but you get the idea).

Just thought I would post back here with my result:

After playing with linux some more and geting some more experience... i ran

dmesg | grep irq

and sure enough my network adaptor (ep0) wasn't getting an IRQ (IRQ 10 in use!), and my PCI card was using irq 10.. went into the PnP part of the bios, reserved IRQ 10, and everything is super...

thanks guys!
