your ISP.
z Bridge: Enables or disables bridging between the device and your ISP.

Protocol messages it receives to the LAN PCs. You must enable the LAN or USB
interfaces for IGMP.
z IP Address and Subnet Mask: If your ISP has provided a public IP address to your LAN,
enter the address and the associated subnet mask in the boxes provided. (Note: In
bridge configurations, the public IP address may be entered on your PC rather than on
the ADSL/Ethernet router; check with your ISP.).
z Use DHCP: When enabled, your ISP will use DHCP to assign an IP address to the WAN

assign an IP address to it. See the appropriate WAN interface help topic for PPP or EoA
interfaces.

Configuration Manager.)
z Use DNS: Specifies whether the DNS server addresses that your LAN will use should be

If you click Disable, you must configure DNS addresses manually on each PC or in the
fields below.
z Primary/Secondary DNS: Specifies the Primary and Secondary DNS server addresses
provided by your ISP.
