martino-cisco · ‎05-05-2016

Hi All,

Please can I get some assistance with problems configuring a 3G router. APN, Username, Password and Authentication have been provided. I can't get an active profile to work still.

Profile 1 = INACTIVE

Access Point Name (APN) = wap.vodafone.co.uk
Authentication = PAP
Username: wap, Password: wap

Running config is below:

hi,

could you try these commands?

no chat-script gsm "" "atdt*98*1#" TIMEOUT 30 "CONNECT"
chat-script gsm "" "AT!CALL" TIMEOUT 20 "OK"

interface Cellular0

no ip nat inside source list INTERNET-ACCESS interface Cellular0 overload
ip nat inside source list 1 interface Cellular0 overload

dialer-list 1 protocol ip permit

Hi John,

Thanks for your response. I finally cracked it using the Dialer0 interface. To be honest, I still can't tell when to use or not to use the Dialer0 over the Cellular0 interface.

See configs below...for anyone who may need this at some point.
