I am trying to configure 'HWIC-3G-HSPA-G' card in a 1921 router, using a UK Vodafone SIM card. I have a client connected to the GE 0/0 interface and I am trying to access the web from that client.
Connected to the console port on the 1921 I can see the profile is active because the sim has received an ip address from the carrier. From the console I can ping successfully any website. My problem is I cannot perform the same ping from the client connected to GE 0/0 therefore I suspect a problem with the NAT configuration on the router. From the client I can ping the GE 0/0 interface so traffic is getting to that point. Please find below my config, an suggestions much appreciated.
