Cisco 5020 L3 routing to gateway device

Jason White
Level 4
Level 4

I have a 5020 setup with inter-vlan and am able to ping devices across the vlans. I am also able to ping the outside 8.8.8.8 from the 5020. If I point an end device to use the 5020 for the gateway it can't ping past the 5020. There is a firewall connected to the 5020 in vlan 100. I have also connected a router up to the 5020 and if I make the end device gateway the 2821 I am able to get out through the firewall.

interface Vlan100
no shutdown

Is the end device in vlan 100 ?

If not then does the firewall have a route for the end device subnet pointing back to the switch ?
