Internet on Cisco CBS350 (DHCP Server on Switch)

[ApplicationError]

I've just picked up a brand new Asus router, which is connected to a Starlink ethernet connection (bypass mode for Starlink). The DHCP on the Asus router is disabled because I want to keep all that on the Cisco Switch -- there are a bunch of PoE security cameras and other mission-critical devices on the switch.

My devices on the Cisco CCBS350 don't have internet.

Any ideas?

Router = 192.168.1.120 (DHCP disabled)
Cisco CBS350 = 192.168.1.254 (DHCP enabled 192.168.1.1 to 192.168.1.200)
Port on Cisco CBS350 for the router is set to Trunk

Hello,

post a schematic drawing of your topology, showing how your devices are physically and logically connected.

You seem to have a flat network (just one subnet) so only your ASUS router will do IPv4 routing. For this reason, you can just use its IP address as the default gateway. In this particular case, changing the default router IP address in the DHCP network pool from ‘Auto’ to ‘User Defined’ with the value of 192.168.1.120 (ASUS router IP address) should resolve the issue.

Also, there is no need to have a trunk on the link with your ASUS router since this router is not VLAN-aware. Use an access port instead.
