Hello to all,
I have a Cisco router 1941 and i need to configure 3g backup. I have got all most every thing to work,WAN link fails 3G comes up, everything seems to be okay, i can ping from router but when i try to ping from PC, it fails. So i think there is someting wrong with my floating default route. I tryed searching from manuals how to configure it, but every manual that i found from cisco, did it with ATM or Dialer0 interface, but i do not have ATM line nor Dialer0, because i do not want persistant 3g connection, so i´m stuck.
Can please anyone help me to get this working ?
