I have applied the following configuration on my internet router my ADSL interface is up and the link protocol is also up but still is not getting an IP address and as consequence not able to communicate through it to my ISP nor to the internet. The configuration I have is:
encapsulation aal5mux ppp dialer
dsl operating-mode auto
ip address x.x.x.x 255.255.255.248
ip nat outside
Please let me know whether this ADSL configuration is alright or I need to fix anything in it.
