DFL-900/1500 User Manual Chapter 1

Quick Start

Transparent mode

Transparent mode provides the same basic protection as NAT mode. Packets received by the DFL-900/1500 are

intelligently forwarded or blocked according to firewall rules. The DFL-900/1500 can be inserted in your network at any

point without the need to make any changes to your network or any of its components. However, VPN, NAT, Routing and

some advanced firewall features (such as Authentication, IP/MAC Binding) are only available in NAT/Route mode.

Note:

1. You cannot connect the LAN1/LAN2/DMZ interfaces to the same Hub while using Transparent mode, otherwise the

traffic from the PCs under LAN1/LAN2/DMZ interfaces may be blocked.

2. If you would like to change the operation mode from NAT/Route mode to Transparent mode, you have to backup the

configuration file and then do the factory reset first.

3. If the DFL-900/1500 is regarded as a proxy server when you enable content filter, etc. in the transparent mode, you

should assign a public IP (WAN IP) and the gateway IP to it in order for the device to access the internet.

as Virtual Server, VPN, Content Filter, and IDS)

can only be available while using Default WAN

link.
