The name depends on chipset of the card. I found this odd at first myself but it can be quite convenient when you need to distinguish between different interfaces; anyway, that's pretty easy to deal with. > gateway of 0.0.0.0 and unfortunately BSD is completely unwilling to accept Your gateway is 0.0.0.0 ? That's . . . um . . . rather unconventional, isn't it? I thought that was a reserved (illegal) IP address. In fact, I'm really pretty sure that it is.

What you want for your machines gateway is the address of the your router--the one immediately upstream from you. It's *that* router's job to route the packets upstream from there. However, in my experience this all the works same way under Linux as it does under FreeBSD. Granted my Linux experience is rapidly deteriorating, but certainly a year or two ago they weren't radically divergent. In both cases (heck, in *all* cases and all O/S's), the default router of interest is the one just upstream from you--that's the whole design of the internet protocol (IP). PS: The easiest way to configure an individual machine, if you can, is to just use DHCP and let it do the configuration for you. Is your router a DHCP server? If so, just set DHCP on the interface in your /etc/rc.conf and it'll work "like magic" just as in Windows or Linux. This *was* a choice from the installer. I'm quite sure of that--it's the way that I always install. > At any rate, I have exhausted the limits of my expertise (which is limited > by my Linux experience of 5 years), and I'm now ready to hire somebody. > > Can you recommend anyone in the greater Seattle area?
