Dear All
I dont know what I am doing wrong at the moment. Seeking your help
I got a 2921 ISR Router with 4G-LTE-G (EHWIC) card working perfectly earlier.. Recently I saw the modem firmware update for 4G-LTE-G and tried to upgrade the firmware. During the update I came to know that the newer firmware is only supported on IOS 15.3 or latest (I was having 15.1). I upgraded to 15.3 and since then I am unable to use the 4G module. Following is my old working config... Please have a look and advise what changes do I need to get it working...
after the upgrade, i tied to use cellular directly instead of Dialer... in both scenarios I am getting the IP address on the WAN side but unable to NAT... no ping from console as well
Building configuration...
