I'm having some trouble with a 2960-S configuration to reach the internet. I'm not sure if this is related to the switch or possibly the comcast gateway. Network configuration is as follows:
Comcast Gateway ---------> Cisco 2960-S -------------------> PC
Public IP / 10.0.0.1 10.0.0.225 (VLAN1) 10.0.0.100
10.0.2.225 (VLAN2) 10.0.2.100
From 2960-S: I can ping private IP of Comcast Gateway (modem), but cannot ping the WAN address. I cannot ping any internet addresses from the switch. The default gateway for users is the VLAN interface on the switch. From each VLAN I can ping the other interface on the switch.
I have ip routing enabled and a static route of 0.0.0.0 0.0.0.0 10.0.0.1
I have a suspicion that the issue may be comcast gateway modem, but wanted to rule out my switch config first.
thanks.
