Can get IP address but no connectivity over port 2

Widget

Level 1

I have the below on a cisco Catalyst C8200L-1N-4T. I can get an IP from the pool VoIP but I get no connectivity to the outside world. This is currently isolated from everything else as it would bring the network down.

@Widget Got it, Thanks for the update.
I don't see NAT config on device, you may need to do NAT to route local-IP to public-ip for route traffic on internet.

@Widget From DHCP Pool Config, Default gateway is 10.93.32.129. is this IP configured on any of your internal device ?

Either would request you to configure 10.93.32.129 on interface GigabitEthernet0/0/2.

After menitoned change still you facing issue, would request you to share trace-route from end device.

Gig0/0/2 auto picks up the 129 address from the pool as it finds itself as gateway. When I ping 129 It gets back correctly, any ping to external I.E. 8.8.8.8, 173.167.177.81, 208.95.26.145 comes back as destination host unreachable.

@Widget Got it, Thanks for the update.
I don't see NAT config on device, you may need to do NAT to route local-IP to public-ip for route traffic on internet.

I am wondering if my static routes:

ip route 0.0.0.0 0.0.0.0 208.95.26.145
ip route 0.0.0.0 0.0.0.0 173.167.177.86 200

are what is messing me up. I pulled the IP addresses from ISP gateways. It looks to me like traffic is not getting from gig0/0/2 to 0/0/0 or 0/0/1 as intended.
