The simplest RRAS Question!

I have W2k Adv Svr…Here is the everyday Joe Shmo setup:

DC1
——–
Nic 1-192.168.129 (DHCP) Connected to Internet
Nic 2-10.1.1.5 (LAN IP Address)

I ran RRAS, set up the ICS via NAT with all the defaults. Ok, now either these step-by-step guides are wrong or im stupid. Everythign was done to the letter. yet none of my LAN machines can access the internet.

My associate tells me its my gateway address. I dont think so. I have the gateway ip address as 10.1.1.5 for the LAN nic. (This was set in the DHCP Sanp In). Is he wrong or am I wrong?) I dont think I am supposed to put the public nics address as my gateway do I?
