Ip addressing issue

[Guest]

I have two networked computers (xp pro and xp home). They are working
together okay.

Computer 1 has a static ip of 192.168.0.1 on the LAN while the other has
auto ip set. If I use 192.168.0.2 I lose the ICS aspect on that second
machine. If I change the first machine to use dhcp I lose my LAN connection.

I can't see why this is working this way. I know I must be missing something
somewhere in there. I should be able to use dhcp on both right? I'm also
using the necessary netbt to enable file sharing etc.

If Computer 1 is sharing its Internet connection, you must not make
any changes in its LAN IP setup.

If you assign a static IP address to the second machine, make all of
these settings:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1 or your ISP's DNS server

[Guest]

thank you for the help. Are you aware that I have two LAN settings. One LAN
setting is the adsl modem router. The other LAN adaptor is the NIC for the
LAN. So I have LAN2 and LAN. But I understand you mean to put these settings

 

[Guest]

also, can you tell me why I am unable to use obtain an ip address
automatically for the two networked computers. When I use these settings I
lose the LAN connection between the two.

 

[Guest]

ok I tried using this setup but lost my internet connection.

Machine 2 is sharing adsl off machine 1. On machine 1 if I enter all the
details you said machine 2 loses it's adsl ICS connection. On machine under
network connections I have LAN 2(internet gateway), and LAN (Realtech
adapter). On machine 1 I have the 192.168.0.1 and 255 255 255 0 subnet. But i
can't put in gateway as 192.168.0.1 or dns address as the that as i lose my
connectivity. I don't understand why this is or why I can't use dhcp on the
local area connection.

On Machine 1, the network adapter to the ADSL modem should be set to obtain
an IP address automatically. It it is not, you will not get a connection to
the Internet.

On Machine 1, the network adapter connected to the LAN should be assigned
by ICS as the shared Internet adapter. Do not fuss with this adapter
settings; ICS should assign it IP address 192.168.0.1 by default; leave it
so.

On Machine 2, either let it obtain an IP address automatically, or follow
Steve Winograd's instructions to set a manual IP address. This is the only
computer on which you would need to follow Steve's instructions.

I wonder, though; why not just get a router with a four-port switch?

I will get the 4 port switch, best advice yet. But what was throwing me off
the track here was how D-Link, in all it's blurbs, talks about this 502T
modem-router as though it can share adsl line with other computers because it
is after all a router. So I am thinking there must be something in the design
of it to share adsl. Otherwise, why is it called a router?

A router connects two IP subnets. NAT routers, in general, include a switch
(with 4 - 8 LAN ports), though apparently yours doesn't.

The DSL-504T, the D-Link current product, includes a 4 port switch. Some older
routers (modem-routers) were sold with no switch, just a single Ethernet port.

According to the product manual, the D-Link DSL-502T is a DSL
modem/router:

ftp://files.dlink.com.au/Product%20Info/DSL-502T/Manual/DSL-502T%20Manual%20v3.00.pdf

To share the DSL connection with multiple computers, connect the
uplink port of a network switch to the 502T's Ethernet port, and
connect the computers to regular ports on the switch.

Ah. Well, I don't recall any mention that the device was billed as a
router. I am not familiar with that model, but I once had a loaner from my
ISP; a Netopia router. You should be able to find a configuration menu for
the router which will set it to DHCP mode. In that case, all that you would
need is a switch (or hub; but switch is better).

Don't use ICS. Use uplink port on switch, or cross over cable if switch has
no uplink port, or can't auto-sense the connection; cross over cable as a
last resort, if all else fails. Connect each computer to a LAN port on the
switch.

Check the D-Link manual.
