Subject: Re: bridging firewall
I'm trying to work out how to build a bridging firewall using a Dell 833
with 512MB RAM and up 3 Nics when the "outside" is via a USB Speedtouch
330. In other words can i tie the usb bus to the nics on the pci bus in
anyway? All I can find so far are how to's that use 2 nics etc that get
outside via a hub/switch etc. Can iptables/ipchains be config'd for use
with a usb ADSL modem and an ethernet nic?
it shouldn't matter that some of your network devices are PCI NICs and one
is a USB adsl modem... the bridging functionality is in a higher layer
(network) than that driver layer.
i wouldn't expect the configuration of this bridge to be significantly
different than bridging between two plain old network cards.

bridging is a MAC layer process not net layer (IP) eh? - even so - how do I
config a USB device as you would a nic eg :
# ifconfig eth0 x.x.0.254 ?
Ive looked in /dev/usb but found devices beginning ez and lp along with the
named devices like scannner, or is the IP assigned to it's USB device
number?
