can you have ICS *and* filesharing?

[Guest]

I have a host (WinXP home) and client (WinXP Pro) connected by crossover
ethernet. The host sees the client, but the client cannot contact the host,
still... I can exchange files that way.
But when I installed ICS, though I had internet on both PCs, it messed up my
filesharing. I could have known from this warning on a site:

WARNING #1: When you enable ICS, the network adapter connected to the local
area network is assigned a static IP address of 192.168.0.1. The client
computers are assigned other IP addresses in the 192.168.0.x range. These
addresses may not be compatible with an existing network.

Now I am back to where I can share the files, but not the internet...
The question is: can I have filesharing as well as internetsharing?
And if yes... how?
My internet IP is fixed, and I am willing to choose all IPs by hand, but
how? and which?
Thanks in advance!

(All MS tells me is that "it's as easy as plugging an appliance into the
wall"!)

Yes, you can have both file sharing and Internet sharing.

Run the Network Setup Wizard on the host first, enabling ICS on the
desired connection. Tell it that you'll select your own local area
network connection, and un-check all connections except the one that
connects to the other computer.

Then, run the Network Setup Wizard on the client. If it detects the
shared Internet connection, tell it to use it. Otherwise, tell it
that this computer connects to the Internet through another computer
on the network.

Don't configure any TCP/IP settings manually. Let the Wizard do it.

Thanks Steve, please let me reply below

I just got ICS to work again... and of course it messed up the filesharing
on the LAN again. I'm afraid the wizards do nothing for me but switch between
internet sharing and file sharing.
Could you be very specific how and where to set which options? I would love
to solve this one

As far as I know that's what I did, with the above result. ("funny" how the
word wizard implies the magical/unlogical behavior of the PC...)
Again, if you could be very specific about what to click I will definately
do my best to try! By the way, my IP for the internet is fixed. Can't I fix
all of them instead of having them automatically adjusted to conflicting
values for file sharing and internet sharing?

Thanks in advance

You're welcome in advance.

Configure your Internet connection's IP settings as specified by your
ISP.

Don't make any manual IP settings on the local area network
connections of the host and client computers -- that can prevent ICS
from working. Let the Wizard configure them. The settings that it
makes should like this, and they'll work for Internet sharing and file
sharing:

Host:
IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Default Gateway: none
DNS Server = none

Client:
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

Steve,
You can't tell me that it works, cause I wouldn't post this problem if it
did work.
Right now I have ICS working. Please tell me how where to change settings to
get the filesharing to work without losing the ICS. And sorry, I tried it
with the wizard, and it messes up the ICS, so it is not an option anymore.
I have 2 new PCs, WinXP on both, a PhD in applied physics and a lot of
perseverance. There must be a way with your help?!
Why does Microsoft want it to be so difficult/impossible ?
Microsoft says ICS messes up your LAN settings and they are right about
that, but how do I solve it?

 

[Guest]

In addition: on both server and client the tray icon indicates that the LAN
is up and running, but I can't connect to a shared folder...

 

[Guest]

another not unimportant addition:
As the previous post seemed to imply: it was a problem of firewalls (somehow).
So the main thing to keep in mind seems to be to open the server to
communication from any client with IP adresses in the full range you posted
before:
192.168.0.x

Problem partly understood, but solved... for now.
Main advice: turn firewalls completely off, then see how far you can close
it again without losing functionality (i.e. configuring it for IP
"exceptions").

After using both filesharing and internet sharing for at least an hour the
filesharing gave up spontaneously... What can cause this sort of thing?
The symptoms are as before

 

[Guest]

Through endless trial and error I have determined that I can get the
filesharing to work (for a little while), when I turn the Norton firewall on
the host off and on again (without changing the configuration!).
Steve, have you got any idea how this can be, and how to fix it for real?
Like I said: I have opened it to 192.168.0.x

My two cents - forget ICS and spend a few bucks on an inexpensive
gateway/"router"/firewall appliance like a Linksys/NetGEAR, etc. This device
will do NAT and DHCP - and they usually come with a small hub/switch built
in - so you don't need crossover cabling between PCs anymore either. This is
far easier, adds more security, and just plain works.

Do not believe marketing weenies. Computers are not toaster-ovens, no matter
what they want you to think.

So basically I should buy hardware for what you can do with software, waste
my brandnew crossover cable (or see if they wanna switch it for a straight
one), and believe thet THIS time it will be real easy, hmmmm...

Would rather know how to configure Norton firewall and be ready.

Well, to nitpick, all firewalls are software firewalls. I just happen to
prefer the kind that don't live on my workstation and that will protect my
network at the perimeter and do DHCP and NAT and work a d__ed sight better
than ICS.

waste my brandnew crossover cable (or see if they wanna switch it for
a straight one),

My stars, how much did this crossover cable cost?
Note that most of these appliances will come with another patch cable
anyway.

and believe thet THIS time it will be real easy,
hmmmm...

Yes, it will be easy if you plug everything into the right places. I have
walked very computer-illiterate people through this setup over the phone in
a matter of minutes - and you know a lot more than they do already.

Would rather know how to configure Norton firewall and be ready.

I can't help you with that (I don't use it or like it) but perhaps someone
else will. I don't use ICS ever, not even on tiny home networks, and I find
Norton software very bloated these days. Just my $.02

Adds more security? Scripties would have trouble getting by it, yes. Others
wouldnt. ICS works well, is easy to set up and not hard to harden. Cant see
why people have such problems with it.

Disable Nortons firewall and download Zone Alarm Pro 30 day free trial. If
it works and you like it, buy it.
