What am I missing her, probably a lot?  Goal: Create 3 scopes within WS 2012R2. 1. Default network (192.168.1.0Range .100-.254) 2. Network for IP Camera system (192.168.2.0Range .100-.254) 3. Guest Network (192.168.3.0Range .100-.254).  Scopes are already created and the default network is operational.

Equipment:  WS 2012R2(DNS 192.168.1.5), Cisco RV042(Internet Gateway 192.168.1.2), Qty. 2 ISPs modems bridged feeding the RV, Cisco SF200-24FP (192.168.2.1 Poe for IP cams), Netgear JGS524E (Not Managed, Default network switch).

Configuration:  the RV is checked as a gateway, with multiple subnets engaged and the subnets have been added. DHCP Relay is engaged and pointed at the DNS Server IP. Port configuration: Ethernet Ports 1&2 VLAN1, Port 3 VLAN2, Port 4 VLAN3.

Problem:  When I connect PC to either VLAN 2 or 3, I do not get a DHCP of 2.100, or a 3.100 I get a 1.100.  Basically why does the server not issue the proper IP when I am connected to VLAN 2 or 3?  So if I static my machine to 2.100 with gateway 192.168.2.1, and DNS 192.168.1.5 I connect to the network, cannot surf and get error cannot communicate with primary DNS server 192.168.1.5.  In closing how does the server know that IP range 2.100-.254 is suppose VLAN 2?

Hi,

Please try to perform a network capture on the DHCP server.

We can check the giaddr field in the DHCP DISCOVER message. This field contains the Relay agent's IP address, DHCP server uses this field to find the suitable scope for the client. This field should be set to the IP address of the VLAN interface.(The gateway of the VLAN).

If this field is set to any IP address in subnet 192.168.1.0, the client will get the IP address from your fist scope.

If this field is set correctly, please check if there is any related warning in the event viewer of the server.

Best Regards.
