Problem with ICS

Hi,
I just have built a small home network (3 clients + host), using an ICS
The network architecture is the following:

(Cable Modem)-->(Host PC - NetAdapter#1+NetAdapter#2)--->4Ports Hub-->Clients

The host Pc is running under W2K-Pro, one of the clients is running under
W2K-Pro and two others under XP. They are configured under one Workgroup.
The host PC can see and share info with clients, and clients also see the
host and they can see each other on the LAN. The hostPC have access to
Internet and have settled ICS, but the clients can not have access to
Internet even they see the host machine.
All the clients are configured with a static IP addresses begining with
192.168.0.2 to 0.4.
The second netAdapter on the host Pc have IP address 192.168.0.1,
subnetmask: 255.255.0.0. The first adapter having Internet conection is in
automatic IP mode.
I have read all the recommendations in the help menu, but no one have helped
me to solve this problem.

Somebody knows where is the error there? I'll appreciate any help.

Have a look at this:

or this (same link)

What netmask and gateway are defined on the clients?

ICS usually prefer to allocate network information itself,
via DHCP. If you can, try changing the client definitions to
DHCP.

It took me a while to understand this but here's the problem...

It is NEARLY impossible (but you CAN if you want though it's certainly not
easy nor fun and it's really quite buggy) to use ICS with static IP
addresses.

So, here's a bit of info...

Box A = Host
Box B, C, D, etc are Clients

Box A is configured to perform ICS and MUST have an IP address
(automatically assigned when ICS is enabled) of 192.168.0.1.
Box A handles DHCP meaning that it then gives out the IP addresses to the
other systems.
Box B, C, D, etc then must have it enabled like a "normal" connection
meaning that they aquire an IP address automatically.
Box B, C, D, etc also have no default gateway.

In that configuration it tends to work. A few rare exceptions require that
the DNS be changed but that's not often. With a small home network the above
is generally what you'd want to do.

Drop the idea of using ICS altogether. Get a Cable.DSL Router such as a Linksys BEFSR41.
there are *many* advantages to using such a device. One is to block TCP and UDP ports 135 ~
139 and 455 which will provide you greater security and mitigate the threat of Internet
worms that attack via these ports.
 
Hi Galen,

I've followed step by step your recomendations, but it diden't work.
I'll treat to give you a more clear picture on this problem

The host has 2 adapters - the first one is conected to cable modem and has
access to the Web. It works properly. It is configured in automatic IP mode
and automatic DHCP and ICS service is available on its setup. The second one
is conected to my LAN (3 clients). When I configured de ICS service on the
host the second adapter got automatically the IP address 192.168.0.1, subnet
mask 255.255.255.0 and nothing more.

You recommended me to set all the clients to automatic IP address and
automatic DHCP, I did that, but the results were awful. Clients did not
reconize each other. The ping command shows that comunication among machines
was broken. So I've returned to the old configuration, stablishing static IP
addresses on the clients.

Now the LAN works properly, it's means the machines respond to the ping
command, including host machine. They can share folders, files, printers, but
clients can't see the Internet trought the host machine.

Some time ago I've installed on my host computer W'98 SE and all my clients
had access to the Web trought the host machine and the clients were
configured on automatic IP mode, but I decided to intall on the host W2k and
Norton Works 2005 and after that the ICS stoped work.

So, you got more clear picture on this problem?

Jorge
 
Hi again,

I've make some experiments with my network settings and have discovered
interesting thing.
I've disconected my clients fron the LAN except one and did some experiemnts
on it.

I configured the client with a static IP address 192.168.0.2 subnet mask
255.255.255.0, no default gateway and WINS=192.168.0.1 and I configured the
second adapter on the host computer with a WINS=first host adapter IP address

After that I opened IE on the client computer and configured its internet
options to have a proxy server with address 192.168.0.1 then executed IE and
observed the network icons on the host's task bar and "voilá " the client and
host were communicating some way but the client can't go out to the Internet.
To prove that I picked up on the icon "home" to force IE searching of home
page and the results were the same...exists communication betwen host and
client but client can not go out to the Web.

I think the problem is on the host and not on the client, but I can't
determine where.

Jorge

This is all that you'll visually see.

When you do this and boot up the client computers, what IP addresses
do the LAN adapters acquire? They should be in the 192.168.0.###
range. If they're in the 169.254.###.### range, then the DHCP server
isn't working.

Firewall an issue? What is the addresses being given out to the connecting
computers? Is there a logical reason for a router to not be involved?

Exactly !

I am guessing 169.* addresses. Even today dial-up enabled routers are
available, albeit scarce but available. ICS is a great idea but, well, not
the easiest thing on the planet to do. In this case - from the looks of
things - they OP can perhaps use assigned IP addresses but will need to set
the DNS to the 192.168.0.1 addy and will probably have to mess around with
DNS settings in advanced and even that is going to be far more effort than
it's worth IMHO.
