I'd like to start off saying that I'm out of my scope here, but I could really use some help. Our ISP gave us the following to connect to our business class internet services.
- Network: 97.105.48.72
- Gateway: 97.105.48.73
- Useable: 97.105.48.74 thru 97.105.48.78
- Broadcast: 97.105.48.79
- Size: /29
- Subnet: 255.255.255.248
- TWC DNS1: 209.18.47.61
- TWC DNS2: 209.18.47.62
I'm using a Cisco 3845 running IOS 12.4(13r). I have the switch ports on VLAN 10 getting served DHCP addresses from the router. That part seems to work fine. I have the connection from the ISP going into GigabitEthernet0/1, assigned 97.105.48.74. I'm able to ping out to the internet from the router. I tried to set up PAT from VLAN 10 to GigabitEthernet0/1. This is where things fall apart. End devices can ping 97.105.48.74, but not the ISP gateway or anything beyond.
Could someone check out my config and let me know if they can spot any obvious errors? I'd really appreciate the help and I expect that my error is a simple one due to ignorance. Thank you very much.

? By the way, you don't need to exclude192.168.1.1
since that is the router address, which is automatically excluded. – Ron Maupin♦ May 12 '16 at 19:31no ip routing
