NAT - Applying B/W limitations - URGENT!

[SauM]

1 - How can I use NAT with only ONE NIC installed under
Windows 2000 Advanced Server?

2 - I'm sharing a DSL connection with a small LAN using NAT
with two NICs installed. Now, how can I limit the B/W
using by some of users or computers?
I tried QoS but nothing happened!
Should I use a third party software or there is a
built-in capability in the Win2K A/S?
I know that RAS can do so using BAP but how can
set it for NAT?

I can't think of any way to do NAT with one NIC. Even if you could multiNet, your internal LAN would be exposed completely to the external network...there's no forced path through a filtering machine/device.

QOS wouldn't work because it has to be explicitly asked for by the application. You could concievably remove a certain amount of bandwidth, but everybody would be limited to the same amount of available bandwidth. I believe the switch you're connecting to also has to support the same QOS protocol in use by the host/client.

NAT doesn't do bandwidth stuff, it just translates addresses.

FWIW

It's possible to do NAT with only one NIC, I simply did it under linux, because
only the TCP/IP layer is responsible for it not NIC and we can do it with only
two different IPs even on a single NIC.

If QoS can not do such thing, which third party software I can use for this
situation? there must be solution!

No more comments or ideas?

I'm interested in the bandwidth limiting also, since i'm sharing a dialup connection, and when someone on the other computer starts downloading stuff it hogs all of the connection, which really slows things down for me.

(that's a long way of saying bump )
