Hello All:

I have finally gotten DSL with a Westell modem. My question is this:



I have the modem set to “Bridge Ethernet†connected to a router. I have 5

computers (2 are Linux). One of them is a WIndwos 2000 server (DNS,AD) How

do I set up the IP address for each machine. The router is set for DHCP

which I do not want. The DSL modem's local IP is 192.168.1.254 and the

router is 192.168.1.150. So, my server is static at
IP: 192.168.1.100
mask 255.255.255.0
DNS 192.168.1.100

Gateway - this is my question is it the routers IP or modem

So basically the rest of the computers will be like the server except the
IP's will be 192.168.1.1 thru 192.168.1.5 Again, I want to disable
DHCP in the router and assign the 5 machines static IP's but I am not
sure how to configure the gateway since this is my way out to the Internet.
So currently my router is still configured for DHCP so when I ipconfig /all
on a windows client it returns
This:
IP: 192.168.1.1
DHCP: 192.168.150
Gateway: 192.168.150
DNS: 192.168.1.150

When I tried to statically assign the IP settings with the same above, I was
not able to get out to the Internet but the DHCP does. See I don’t want the
router to assign IP’s because of the server which is my local DNS.

Odd. Could you even ping your router's LAN IP at 192.168.1.150 then?
See I don't want the router to assign IP's because of the server
which is my local DNS.

Hmmm. That shouldn't stop you from using DHCP at all. I think static IPs for
workstations are a pain, even on a small network. I suggest you just disable
DHCP in your router and install it on your domain controller instead....

003 Router (internal IP of your router - 192.168.1.150)
006 DNS servers (LAN IP of your DC/DNS box - 192.168.1.100)
015 DNS Domain Name (e.g., mydomain.local)
044 WINS/NBNS Servers (LAN IP of your WINS server if you run it -
192.168.1.100)
046 WINS/NBT Node Type (0x8)

You may not be using WINS, but I usually recommend it. .

You mean the router is configured to be a DHCP server, right? If you don't
want it to do that, there should be a setting somewhere in the router
configuration to turn it off.
The DSL modem's local IP is 192.168.1.254 and the

If the DSL modem is set to bridge, it shouldn't have an IP address (local or
public). By definition, a DSL modem bridged is an Ethernet-to-ATM protocol
converter. It's a layer-2 device. Your own router should have a public IP
address on it's WAN interface and a private one on it's LAN interface.

router is 192.168.1.150. So, my server is static at
IP: 192.168.1.100
mask 255.255.255.0
DNS 192.168.1.100

Click to expand...

As stated, the modem shouldn't have an IP address if it's bridged. The
router should be your gateway.
So basically the rest of the computers will be like the server except the
IP's will be 192.168.1.1 thru 192.168.1.5 Again, I want to disable
DHCP in the router and assign the 5 machines static IP's but I am not
sure how to configure the gateway since this is my way out to the
Internet.
So currently my router is still configured for DHCP so when I ipconfig
/all
on a windows client it returns
This:
IP: 192.168.1.1
DHCP: 192.168.150
Gateway: 192.168.150
DNS: 192.168.1.150
Click to expand...

The router is acting as a DNS proxy. It's odd that a router would be at
192.168.1.150 by default. Most routers are at .1 out-of-the-box, with a few
at .254.

If your router has a 192.168.1.x IP address on both the private and public
Interfaces, it won't be able to route.

Here are a couple of questions that will help:
1. What is your public IP address?
2. What is the Router's WAN IP address, subnet mask, and gateway?


A Bridged DSL connection requires that your ISP configure their end, since
99.9% of clients will want their DSL modems to also be their routers. This
can be set up statically (usually by the circuit ID - phone number - that
your DSL is connected to. It can also be set up to be dynamic, where your
router will request the DHCP address from the ISP's pool, and the modem just
passes the requests along. Different ISPs use different methods of
authentication. You may have to configure your credentials on your router.

This is confusing, the modems IP is 192.168.1.254 and the routers IP is
192.168.1.150?
Is this a PPPoE DSL? If it is I must assume the modem is doing the
authenticating and getting your public address on its WAN connection.

Is this (192.168.1.150) the routers WAN address or LAN address?

The WAN address and LAN addresses must be on different subnets for the
router to work. If 192.168.1.150 MASK 255.255.255.0, is the routers WAN
address change the LAN address of the router to a different subnet like
192.168.2.1 Mask 255.255.255.0, then give all the clients connected to the
LAN side of the modem an IP in the 192.168.2.x subnet with a mask of
255.255.255.0 with the routers LAN address as the Gateway and the DCs
address for DNS.
