How to set up routing between two ports through the server?

Question

System administration

There is a Windows Server 2008r2 Server, a switch, a router. The server has two network ports. 1 port 192.168.1.2 255.255.255.0 gateway 192.168.1.1 (connected to the router ip 192.168.1.1 ), 2 port 192.168.1.3 255.255.255.0 gateway 192.168.1.2 (connected to the switch). The task is that the first port would receive the Internet and redirect to port 2, and that port would already distribute the Internet to everyone else.

Answer 1

Raise the routing service and DHCP server on the server.
But it is not clear why such crutches.
It is more logical to raise DHCP on the router and distribute from it, to the server and to clients.

Answer 2

Due to the use of the same subnets, an address conflict is likely.
It won't work.

Answer 3

different networks are routed, the same ones are switched ;) assign an address from another network to the router
, for example 192.168.2.100, respectively, on the server, write 192.168.2.1 Set up, work.
