Transparent - D-Link DSR-150 User Manual

Section 5 - Connect to the Internet
When Transparent Routing Mode is enabled, NAT is not performed on traffic between the LAN and WAN
interfaces. Broadcast and multicast packets that arrive on the LAN interface are switched to the WAN and vice
versa, if they do not get filtered by firewall or VPN policies. To maintain the LAN and WAN in the same broadcast
domain select Transparent mode, which allows bridging of traffic from LAN to WAN and vice versa, except
for router-terminated traffic and other management traffic. All DSR features (such as 3G modem support) are
supported in transparent mode assuming the LAN and WAN are configured to be in the same broadcast domain.
Note: NAT routing has a feature called "NAT Hair -pinning" that allows internal network users on the LAN and DMZ to
access internal servers (e.g., an internal FTP server) using their externally-known domain name. This is also referred to as
"NAT loopback" since LAN generated traffic is redirected through the firewall to reach LAN servers by their external name.
