Hello, I just purchased a control box for a new project at my business. I am using the device to isolate a guest wireless network that will share our business network.

Everything is working great when I only use the trusted/local interfaces. As long as the port is assigned to this group I am able to access the internet with no problems. When I designate a port as Stand alone I lose internet connectivity. Here is my setup.

Internet Interfaces
IP: (Assigned by the ISP router)

Trusted/Local Interfaces
LAN Switch Ports: 2,4 Static IP with DHCP enabled.. I can connect clients to either port 2/4 and get an IP address and also internet connectivity.

VPN Server
Not used

Other interfaces
Port 3 Static address with DHCP enabled..

I get an IP from the DHCP server but no matter what rule I create, I cannot get to the internet through this port. I need to be able to access the internet through this interface because all of the wireless clients will be on this subnet. I am trying to mask my internal IP address from the wireless clients.

Port 3 with destination of firewall with service DHCP/BOOTP = allow
Port 3 with destination of Internet interfaces with service any = allow + Source NAT
Port 3 with destiantion of any with service any = Drop

Any ideas why this wouldnt work? I am receiving IP address which proves the first rule is valid. The second rule is identical to the pre-configured rule for the trusted interfaces which works as well..

Thanks in advance.

I found my problem.. I had to specify the DNS address in the DHCP scope for the secondary subnet. Everything works now. Was a simple mistake.
