Hi Larry thank you for your answer in first place.
Sorry for that Layer-2 switch brings more complexity to this problem. Forget that switch let me simplify this. The server links to internet via a USB modem [Not RJ-45]. I installed sygate home network software to share the connection. Now what I want to do is link 2 pcs to this R1s E0/0 and E0/1 interface, and have R1s E1/0 interface link to server. In order to allow this 2 pcs to surf the internet, I need to enable dns forward/reply on R1(I use static ip addressing).

According to your answer. I assume R1 have the following configuration.

R1#
ip domain-lookup
ip name-server 192.168.0.2
ip default-gateway 192.168.0.2

interface Ethernet0/0 ---- this to pc 1 [DNS point to 192.168.0.2]
ip address 10.0.0.3 255.255.255.0
!
interface Ethernet0/1 ---- this to pc 2 [DNS point to 192.168.0.2]
ip address 10.0.0.4 255.255.255.0
!
interface Ethernet0/1 ---- this to server [ server ip 192.168.0.2/24]
ip address 192.168.0.4 255.255.255.0
ip helper-address 192.168.0.2
!

Hope this configuration works.

Last thing, On the server, add a route for this e0/0 subnet pointing to 192.168.0.4
This will tell the server how to get to those clients. ( via R1 )
Any idea how to do this on windows 2003 ?

Thanks again larry, this really helps.
Chen
