DFL-900/1500 User Manual
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:
Transparent mode
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.
