A network cable by a layer 2 switches, network cable to connect computers by configuring the local IP address can get to the Internet, such as 172.22.27.234 255.255.255.192 mask, gateway 172.22.27.254, DNS 172.22.27.254, now want to connect the network cable to the cisco router, what should do to make the router other mouth by computer can surf the Internet?

Can you move a layer on layer 2 switches? Called the link layer 2 switch interface WAN,
If can't move: the cable after receiving router WAN port, to the router's WAN IP port configuration, and open the NAT, this interface do NAT outbound interface, then the router interface, all with independent addresses (segment can't repeat, each other can't cross) and do NAT the inbound interface, at the same time do this section of the gateway, each interface can connect switch do extension (if you don't need to do a network segment isolation, can grab an interface, to configure IP gateway, do NAT the inbound interface, the switch, in addition to the two interfaces, other interface all empty)
If move: configuration and as above, but don't need to do NAT, also need to do a static router on the upper routing refers to the the WAN interface of the router
