I have three sites. Each needs thier own ip addresses because I will have routers inbetween them. DHCP, local DNS, Wins and the Internet connection are all at Site 1.
Site 1 router is 38.123.123.1
Internet router is 38.123.123.2
Site 2 router is 38.123.124.1
Site 3 router is 38.123.125.1
When I configure the DHCP scopes do I need to put both the Site router and the Internet router for Site 2 and 3?
When I configure the DHCP scopte for Site 1 do I include all four?

No. One gateway is all you need. The routers will have the routes to the other routers and will handle it from there.

You will need to define Scope options for each scope. The gateway IP address (Option 003 Router) should be the local default gateway to each site or subnet. It's from scope option that each site's DHCP clients will get the IP address of their Default Gateway (local router interface).
