I have one of those.
It's supposed to be able to handle multiple fast connections, like T1s
I just don't know how to make use of it, and the port boxes for them are
hard to find. Further, their serial lines are RS-422 and other ports,
so you'd need a conversion to RS-232 I believe.
It just seemed like it was more work than just bying an old PC. I just
hate to do that.

I have never seen one with a backup serial port.
You mean there are some I could just hook my modem up to?
I know there are analog routers, but they seem expensive.
I'd be happy with some form of analog router, and then I could
put a 4-port ethernet card (I have one sitting around) in an
SS5 to gateway to that connection.
I'm assuming the firewall abilities of NetBSD are better than what the
router would have.
