LAN connection problem.

LAN connection problem.

I have tried to build a 3 computers LAN without using
ROUTER and Hubs.

Three LAN card in computer A.
One LAN card in computer B.
One LAN card in computer C.
OS - windows XP

The structure is shown as follows,


Internet
|
|
C ---- A --- B

I want A, B, C to be able to communicate with others.
However, I can sucessfully set C to communicate with A
or set A to communicate with B.
B can't talk to C or vice versa?
Is there any IP, subnet mask, gateway setting
requirement?
Would someone please provide some hints on configuring
such LAN?

Thank you very much!!!!

Boy! you sure do want to play with fire! No
router/firewall and you have an internet connection to 3
computers? you must like to reinstall os' after they get
trashed. Do yourself a favor and trash the 2 extra NIC's
in the one box and put in a small router/firewall/switch
(under $80) Problem solved.

are you on broadband?
if so try this:

a: nic 1 - broadband connection - firewalled, shared, using DHCP from your
isp
dns primary/secondary set to your isp dns ip's (set to auto-detect)
nic 2 - ip 192.168.2.1, sub 255.255.255.0 (connection to b)
nic 3 - ip 192.168.2.2, sub 255.255.255.0 (connection to c)

b: nic 1 - ip 192.168.2.3, sub 255.255.255.0 gateway ip 192.168.2.1
dns primary/secondary set to your isp dns ip's (set manually)

c: nic 2 - ip 192.168.2.4, sub 255.255.255.0 gateway ip 192.168.2.2
dns primary/secondary set to your isp dns ip's (set manually)

don't forget to enable 'mydocs' and printer sharing on each of your pc's
(don't enable root access to your drives - very dangerous if anyone hacks
in) also don't save any private info in the my docs folder, save into a root
folder (unshared)

good luck!

fwiw, I use a 4-way cable router, just set it up and each and every pc I
connect is automatically assigned an ip address, subnet mask etc. and using
a hub have successfully had 6 pc's all connected to the internet, all able
to download at once.:-

internet:-----:router:----------C1
| | \-----------C2
| \-------------C3
\---:hub:-------C4

more PC's if you dare!
