How to connect 2 WAN, 1 LAN through a Cisco router?

“Hi, I need a router, can connect 2 incoming Ethernet line (WAN), 1 output line (LAN), need 10/100/1000 ports. Would you recommend a router for me?” One customer from Chad asked.
Let’s share the solution for everyone.
1)    10/100/1000 ports Router:
1800 series router only have 10/100 Ethernet ports, can’t be chosen.
2800 series router, from CISCO2821 will have 2GE ports.
Description: 2821 w/ AC PWR, 2GE, 4HWICs, 3PVDM, 1NME-X, 2AIM, IPBASE, 128F/512D
So recommend CISCO2821 Router as the reasonable choice.
2)    Connect 2 incoming Ethernet line (WAN), 1 output line (LAN).
Need 3 GE ports, CISCO2821 include 2 GE port, then need add 1 GE ports at least.
a. HWIC-1GE-SFP+ GLC-T (MJ-45 normal cable connection)

b. HWIC-1GE-SFP + GLC-SX-MM/ GLC-LH-SM (optical fiber connection).
