Cisco 881 Router with internet connection and MPLS

[weslykirui]

Hello Members,

I have 881 router and it has 1 WAN port and 4 Fa ports.  My ISP has configured WAN port sub interfaces for both Internet and MPLS. My challenge is I want Internet connection to got through the Firewall before going to the switch. MPLS should directly connect to the switch from the router. How should I connect considering all all other ports are ethernet ports? Below are configs

interface GigabitEthernet0/0/0
no ip address
ip nat outside
negotiation auto
!
interface GigabitEthernet0/0/0.1134
description test INTERNET
encapsulation dot1Q 1134
ip address 41.90.230.218 255.255.255.252
ip nat outside

The text says that you have a WAN port and 4 fa. But the partial config that you post has G0/0/0, G0/0/1, and G0. How can we reconcile these differences?

Your description indicates that in addition to the router there is an ISP, a switch, and a firewall. Can you explain how these are connected? It appears that ISP connects to G0/0/0. But what about the switch and what about the firewall?
