Recently I had a task to configure a internet connection on a 2811 router, but i'm a newbie so not sure i did it correctly.
First of all, my router has only 2 Fast ethernet ports. Also, what's the purpose of backend IPs. Here is the config below (ip has been modified):
ISP config: Router Interface: CAR1.NWR1 PC105
Switch Port: MCD101.NWR1 :interface 1/0/18
Vlan: 141
Front-End IPs: 4.1.1.0/30 (Level3 side: 4.1.1.2, Customer side: 4.1.1.1)
Back-End IPs: 8.8.8.0/24 (Useables: 8.8.8.1 - 8.8.8.254)
My router config:
Current configuration : 1338 bytes

service timestamps debug datetime localtime
service timestamps log datetime localtime
service password-encryption

i didn't create any acl and NAT yet. Please correct my config if it's wrong.
thank you very much!!
