gateway

I have a Windows XP machine acting as internet gateway. It is connected to two different networks, one, say LAN1, connects to internet and other, say LAN2, to outside LAN. My machine is sitting behind the gateway. I have set up internet connection sharing on LAN1 and can access internet on my machine but i can't access anything from LAN2. Is it possible to access internet from LAN1 and yet be able to access PC's on LAN2?

--------------   ---------
| Lan 1      |   | Lan 2 |
| (Internet) |   ---------
--------------      ^
    ^               |
    |               |
--------------------------
|    Win XP Gateway      |
--------------------------
           ^
           |
      --------------
      | My Machine |
      --------------

EDIT: Gateway is equipped with 3 lan sockets, two are connected to Lan 1 & 2, third one is connected to switch. And my machine also connects to that same switch.
