I'm attempting to test out a Verizon 4G backup solution for my companies branch offices, but I'm having an issue getting traffic to internet. The topology is:
Laptop to Cisco 3750
Cisco 3750 to Cisco 2811 (via 802.1q trunk)
Cisco 2811 to Sierra Wireless appliance (connected to Verizon)
From the router CLI, I am able to ping out to several Google.com IP addresses (8.8.8.8, 74.125.25.103, etc.). Unfortunately, whether I connect the laptop through the 3750 switch, or directly to the 2811, I cannot ping out to those same addresses. Here are the configs...
