The Cayman Gateway can be used as a bridge, rather than a router. A
bridge is a device that joins two networks. As an Internet access device, a
bridge connects the home computer directly to the ser vice provider’s net-
work equipment with no inter vening routing functionality, such as Network
Address Translation. Your home computer becomes just another address
on the ser vice provider’s network. In a DSL connection, the bridge ser ves
simply to convey the digital data information back and for th over your tele-
phone lines in a form that keeps it separate from your voice telephone sig-
nals.

If your ser vice provider’s network is set up to provide your Internet connec-
tivity via bridge mode, you can set your Cayman Gateway to be compatible.
tivity via bridge mode, you can set your Cayman Gateway to be compatible.
Bridges let you join two networks, so that they appear to be par t of the
same physical network. As a bridge for protocols other than TCP/IP, your
Gateway keeps track of as many as 512 MAC (Media Access Control)
addresses, each of which uniquely identifies an individual host on a net-
work. Your Gateway uses this bridging table to identify which hosts are
accessible through which of its network inter faces. The bridging table con-
tains the MAC address of each packet it sees, along with the inter face over
which it received the packet. Over time, the Gateway learns which hosts are
available through its WAN por t and/or its LAN por t.

When configured in Bridge Mode, the Cayman will act as a pass-through
device and allow the workstations on your LAN to have public addresses
directly on the internet.

NOTE:
In this mode the Cayman is providing NO firewall protection as is
afforded by NAT. Also, only the workstations that have a public
address can access the internet. This can be useful if you have
multiple static public IPs on the LAN.
