Not receiving IP from DHCP

I have (2) networks going into an ap 1200 - the AP has a static ip set on it as 192.168.199.210 which is vlan 20

the other network is from my DSL to have wide open wireless for guests (vlan100) that ip in the router is set at 192.168.199.51 (scope is set not to interfere)

I get the ssid to the client but fails to get an ip address.

I have vlan 1,20,100 trunked on the switch. what am i missing here. thanks

Re: Not receiving IP from DHCP

You need to have a router to route between the VLANs, specifically from the Native VLAN (where your DHCP service is probably located) to the VLAN 100 segment.

You'll also need to have some kind of IP HELPER / DHCP forwarding on the VLAN 100 client-side of the router pointing to the DHCP service IP address.

Even though the VLANs are physically located on the same device, they cannot talk to each other without a Layer 3 device to pass the traffic from broadcast domain (VLAN) to broadcast domain (VLAN).

Good Luck
