Field Description
Routing Mode Select Transparent.
Save Click save to activate your settings.
When Transparent Routing Mode is enabled, NAT is not performed on trac between the LAN and Option
interfaces. Broadcast and multicast packets that arrive on the LAN interface are switched to the Option and vice
versa, if they do not get ltered by rewall or VPN policies. To maintain the LAN and Option in the same broadcast
domain select Transparent mode, which allows bridging of trac from LAN to Option and vice versa, except for
controller-terminated trac and other management trac.
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 trac is redirected through the rewall to reach LAN servers by their external name.
