I am using a Cisco SG-300 28 port switch in layer 3 mode as my default gateway for all my devices. I have two vlans on the switch, vlan 1 and vlan 4. Both are pulling valid IP addresses in their scope from the DHCP server, and both have valid DNS settings. I set a static route to the Internet on the switch to our firewall (192.168.5.254). All devices connected to vlan 1 are able to access the Internet, however all devices connected to vlan 4 cannot get past the switch. A tracert from one of these devices shows it hits the switch as the gateway, but gets no further. Below is the switch config. Can someone assist with what I am doing wrong?
