Mình có kèm theo mô hình + NAT.
Nếu có cấu hình không được thì kiểm tra đường dây internet bằng cách cắm dây mạng trực tiếp vào máy rồi quay PPPOE để kiểm tra.

Em đã cấu hình thử nhưng không chạy được. đây là file cấu hình của em bác xem giùm em không biết có sai chỗ nào không?

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.


It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.


username <myuser> privilege 15 secret 0 <mypassword>


Replace <myuser> and <mypassword> with the username and password you
want to use.

Cisco Configuration Professional (Cisco CP) is installed on this device.
This feature requires the one-time use of the username "cisco" with the
password "cisco". These default credentials have a privilege level of 15.


YOU MUST USE CISCO CP or the CISCO IOS CLI TO CHANGE THESE
PUBLICLY-KNOWN CREDENTIALS


Here are the Cisco IOS commands.


username <myuser> privilege 15 secret 0 <mypassword>
no username cisco


Replace <myuser> and <mypassword> with the username and password you want
to use.


IF YOU DO NOT CHANGE THE PUBLICLY-KNOWN CREDENTIALS, YOU WILL
NOT BE ABLE TO LOG INTO THE DEVICE AGAIN AFTER YOU HAVE LOGGED OFF.


For more information about Cisco CP please follow the instructions in the
QUICK START GUIDE for your router or go to http://www.cisco.com/go/ciscocp

bạn check từng bước
interface dialer1 của bạn có nhận được IP từ ISP chưa?
ISP của bạn có cần phải reset MAC address không?

[thanhnam0707]

Bạn dùng máy tính quay PPPoE lên ISP thử ok không?

Sau đó bật debug pppoe packet trên router...lên xem thử

[dhieulc]

Bạn thử lệnh

Bạn thử lệnh "show ip interface brief"!
Xem Interface Dialer 1 có nhận được IP wan không

VD:

Interface IP-Address OK? Method Status Protocol

Dialer1 117.6.145.123 YES IPCP up up


nếu như thế này là nhân được IP của ISP rồi!Bạn chú ý thêm ACL cho router nữa
