Re: Any reason for 2nd NIC w/hardware firewall?

Yes, it would be redundant. But then again so is having two power supplies
and redundant disks ;-).

About the only circumstance where you'd purposely avoid two nics would be if
you're using your hardware device as a VPN endpoint. You don't *have* to go
with two nics, but it does give you some additional flexibility, such as an
internet connection point that's outside your lan - which is handy in quite
a few circumstances.

Got it, with this in mind using 2 NIC's and the basic firewall (Standard
Edition) behind a Firebox would be redundant?

a firewall does not just open/close ports, it inspects traffic travelling
through open connections and only allows them to remain open if defined
criteria are met. One of the reasons I prefer SBS Premium is due to ISA
'Application layer' traffic filtering. This means that you can control
not
only the type of traffic but exactly which process requests it. Opening a
port is not necessarily opening a port :-)

It's a firebox, but can you elaborate a bit on the difference?

I know a True firewall gives added protection, but opening a port is
opening
a port NAT or no NAT, isn't it?

And what does the 2 NIC option provide behind a NAT firewall?

Thanks,

The desirability for a 2 NIC setup depends largely on the capabilities

the 'firewall' device.

If it is a true firewall device there is little benefit in running a
two
NIC
solution. (Read WatchGuard FireBox, Cisco PIX or similar)

If it is a simple NAT router (which many incorrectly refer to as a
firewall)
a 2NIC solution is desirable.

Setting up a new SBS 2003 Standard server (is that redundant?),
which
has
two
NIC's, however the 2nd is currently disabled since it's behind a
hardware
firewall/VPN router.

Plans are to allow OWA, and possibly host a website in the future;
all
other
traffic will be via VPN.

Is there any reason to use the 2nd NIC and the built-in firewall on
SBS?

Thanks
