Cisco 9300 connected to Home Router - VLAN's not able to access gateway

[CS100]

Hello I have a Cisco 9300 switch connected to an AT&T Router and able to ping outside (www) from the switch but not able to ping or gain access from any VLAN.

Any Help or Advise would be appreciated. I am trying to eliminate the need of a Cisco Router this is for a home lab

Hello,

make sure the router has a route back to the 192.168.100.0/192.168.200.0/192.168.300.0 networks. You also need to add those networks to the NAT configuration of the router.

Post the full running configuration of the router.

Hello

You will require NAT to allow your lan users access to the internet-

Ive just checked and the CAT9300 does support NAT but it seems on 16.10 train software and only when the switch is stacked -Which i’m not sure why cisco would specify this? here

Cisco Catalyst 9300 Series Switch supports Stacking and NAT is supported on a stack set-up.

So if your switch doesn’t conform to these requirements then you will need a rtr to provide NAT functionality
