1921 to obtain internet from service provider's router

Boo
Level 1
Level 1

Need help connecting cisco to ADSL router to obtain Internet connection. Please assume ADSL modem doesn't have any other functionalities than  just simply getting the internet service.


ADSL router contains username and password to connect to ISP via PPoE

1) ADSL router

ADSL WAN IP x.x.x.x/32

ADSL Router's gateway 192.168.1.254

DHCP enabled - 192.168.1.0/24

2) Cisco 1921 - No HWIC's

DHCP enabled - 10.10.10.0/24

No Vlans at present

(Thinking about creating a router on a stick 802.1Q trunking by adding a seperate subnet for voice in the future)

gi0/0 - ip address 192.168.1.250/24 
            ip nat outside

gi0/1 - ip address 10.10.10.254/24

           ip nat inside

gi0/1 - Switch

Switch to end user devices. 

access-list 10 to allow 10.10.10.0/24 & 172.16.0.0/24

ip route 0.0.0.0 0.0.0.0 192.168.1.254 (Next hop being the ISP router)

ip nat inside source list 10 int gi0/0 overload

Does this setup work ?
