Hi,
I'm not too familiar with tcp ip settings and the way it
works.

My network as a router with an ip address of 192.168.0.1
Right now I am on a computer that has ip 192.168.0.3 which
is able to access the internet no problems.
That computer (192.168.0.3) has 2 network cards.
the first one has the following configs
ip address 192.168.0.3
subnet mask 255.255.255.0
default gateway 192.168.0.1

The config I put in for the 2nd network card is:
169.254.225.164
subnet mask 255.255.0.0
default gateway 169.254.225.163

The second network card is connected with a cross cable to
a laptop.
The config I put in the laptop is:
169.254.225.163
subnet mask 255.255.0.0
default gateway 169.254.225.164

I can transfer files from 192.168.0.3 to the laptop and
vice versa no problems but I don't know what I did wrong
but the laptop cannot use 192.168.0.3 as a gateway to the
router 192.168.0.1 to browse the internet.
when i do a tracert to 192.168.0.1 it gives only * for all
hops.
I know I could connect the laptop directly on the router
but my point is to learn how to make a fully routable
tcpip little lab.
Is windows 2000 pro unable to route without a special
software (something related to NAT) or is it all my
gateway configs that is wrong. I really don't understand
what ip's to enter for gateways especially when there is 2
network cards in a pc (it probably shows in the configs I
gave previously).


Thanks in advance to anyone who can answer my questions.

I have a vague recollection that you can only use Win2000
Server as a router, not the workstation flavour.
 
Your best solution woould be to plug the second PC into your router.

If your OS is a server OS, enable your RRAS from administrative tools. If
your OS is professional, you cannot route packets. First you'll need to
change your IP subnet on the router to something different the 192.168.0.x
ICS uses this. Next enable ICS on the network interface connected to
router.

What if:

The 2nd NIC ran ICS and assigned an IP address to the laptop?
Doesn't ICS use 192.168.1.1 by default?
The other subnet is 192.168.0.1, a different network.

Are you telling me this statement:
My network as a router with an ip address of 192.168.0.1
Click to expand...

....should read:
My network has a router with an ip address of 192.168.0.1?

I completely missed the typo!
