Hello,I think your problem

Hello,
I think your problem might be here:
Profile 1 = INACTIVE*
--------
PDP Type = IPv4
Access Point Name (APN) = abcdef
Authentication = CHAP
Username: abcdef
Password: abcdef
!
chat-script gsm "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
!
interface Cellular0
 ip address negotiated
 encapsulation slip
 dialer in-band
 dialer idle-timeout 0
 dialer string gsm
 dialer-group 1
 async mode interactive
!
Make sure that the resalted information its correct, the profile config it´s wrong. Also check the chat-script, not all chat-scripts works for all carriers, the encapsulation too.
And i think that you should add a route for the cellular interface. Something like "ip route 0.0.0.0 0.0.0.0 Cellular 0 200" if you want to use it as backup.
 
Regards.

Hi Carlos,You are right I

Hi Carlos,

You are right I changed the static route to 0.0.0.0 0.0.0.0 cellular0 and run a ping and the profile came UP. It means that the chat script and the profile is ok.

The issue now is that after the router reboot I need to run a ping from the router first before the profile get activated.

How can I bypass that process!!!

 

Thanks

Sry about the delay! the

Sry about the delay! the profile goes inactive due to lack of traffic. Try making a ping with source (use the vlan, interface that uses the cellular interface as output) and you will see that the profile goes active again. 

Regards!
