Multiple External interface device

Does anyone know of a simple (maybe close to consumer level - Linksys /
DLink / Netgear) router / firewall device that has the ability to accept
multiple PUBLIC external IP addresses? I have 3 PUBLIC address that I would
like to NAT internally to certain servers - including Exchange and Web
server. Thank you.

Cisco PIX501 and 851 router are the cheapest that I know of.

And RRAS or ISA server can both do it.

As well as Netscreens. For the poster, Linksys decices are too low end for
this type of solution.

Hello Bill,

I was not aware of this until you mentioned it - not really thought about
RRAS for this purpose but sounds promising and CHEAP (my ultimate goal- thus
"consumer" level).

Anyhow, I currently have RRAS for VPN already on Windows 2003 and only use 1
NIC (not the recommended two NICS). Will one to one NAT still work in this
configuration - using only 1 NIC to handle all the work of 1 to 1 NAT?

Thanks again!

I doubt it. It is part of the NAT section of RRAS. The pool of public
IPs is allocated to the public interface. It would need to have a direct
connection to the Internet. You can map a public IP to a private IP using
the Reservations button.

If you are currently using VPN with one NIC I presume you are behind a
router/firewall which acts as your public interface.

Yes, I am behind a Cisco Router. I am thinking though that it may be
possible - should be anyhow. I can request the Cisco router to pass
anything on the PUBLIC IP range I need onto the RRAS Windows 2003 and let
the RRAS handle the translation further - speculating here. Still don't
think so?

BTW, The Cisco device we are behind of is not our company's but the ISP's.

You would still need two NICs in the RRAS router. In any case, why would
you want to do this from behind a router? Why would you want a NAT router
behind a NAT router? Let the router do the NAT. You would only use RRAS for
this if it was the Internet gateway.

Shouldn't matter. If it is a "real" router and not a NAT Device posing as a
router, it will not even be involved. What you do on your own side of the
Cisco Router (which is where you public IP#s live) is up to you.
