can NAT work using only one NIC?
Guillermo Krawiec
and my internal LAN hosts. I was only given two public IP addresses(besides
the network and broadcast ones). One I assigned to my ethernet port in the
router, the other I assigned to the w2k machine through its 10bT network
card. I then added a second IP address to the same network card (a private
10.10.10.1/255.255.255.0 address). Now I would like to use the w2k machine
(server) as the NAT. Will this configuration work? How do I get about doing
this? I've been playing around with it, but I can't figure it out.
I have used NAT software before, and what they pretty much did was create a
Private IP address, and assigned it to the server machine, then I was
supposed to set all other hosts to have that private IP address as their
gateway, then the NAT software converted the private ip into a public one,
and shipped it out through the gateway (public address) defined in the
server. It seems w2k works similarly, but i cant figure out how to tell
which is the private IP address to put as gateway.....etc.
Any help will be greatly apprciated.
thanks,

on it.
Somebody confirm or deny this, but I don't think that Win2K can do NAT on
one NIC with two addresses, though I could be wrong (RRAS seems to want to
do things on separate interfaces, and I don't think a NIC with two IPs is
treated as two interfaces -- again I could be wrong). I've had no problem
getting it to work with two NICs, but that's not your question.
If I were you, I'd save the hassle and connect the Cisco (assuming it
doesn't have NAT capability) directly to the Win2K server, put a second NIC
in the server, connect that to the hub, and connect the workstations to the
hub. Assign the range of IPs in RRAS, set the appropriate gateway and
static route settings (per Help), and off you go.

Guillermo Krawiec
doesn't allow me to...
There are several subnets in the LAN and they are all connected to the cisco
router (which doesn't support NAT, at least not with this version ofIOS).
There are several machines in the building (each from a different comopany)
and they all share the same router.
I might be able to add a second NIC anyway and connect to the same hub...I
am just wondering if that might create loops....
I gotta try something, but I hope somebody will tell me how to do it with
only one nic and several IPS...
thanks,

do you want to use NAT? Do you have individual PCs that need to be
accessable over the net (web servers, email servers), or do your clients
only need WWW-type access? My experience with Win2000 NAT has been that for
every PC you want to use NAT to access the internet, you'll need a seperate
address. If you want to use one public address for many users, I would
suggest MS Proxy (and you'll still need two NICs). Win2000 NAT might work,
but you'll need to try dynamic NAT (which so far I have avoided). In
dynamic NAT, your RRAS server becomes the DHCP server (but not a full
featured one).

and some games even work from multiple machines behind NAT (all games should
work if there's only one client playing at a time) like Unreal Tournament.
Using ICS is the easiest, and yes, it acts as a DHCP server.
Using RRAS and NAT you can set up the full-featured MS DHCP Server or use
the limited internal DHCP server (which is part of RRAS).
