MAC Address

The MAC (hardware) address is a low-level network identifier. It may be called "MAC Ad-
dress", "Hardware Address", or "Physical Address". On a PC, this address is associated with
the Network card or adapter. The address on the MAC Address screen is the address on the
Internet (WAN port) interface, and has no effect on the LAN interface.
•
If your ISP asks for the "Network Adapter Address", "Physical Address", "Hardware
Address", or "MAC Address" for the PC the DSL/Cable modem is connected to, provide
this value.
•
If your ISP has already recorded a MAC address, you can change the address used by the
Broadband Router to match the address recorded by your ISP.

Virtual Servers

This feature allows you to make Servers on your LAN accessible to Internet users. Normally,
Internet users would not be able to access a server on your LAN because:
•
Your Server does not have a valid external IP Address.
•
Attempts to connect to devices on your LAN are blocked by the firewall in this device.
The "Virtual Server" feature solves these problems and allows Internet users to connect to your
servers, as illustrated below.
Figure 34: Virtual Servers
IP Address seen by Internet Users
Note that, in this illustration, both Internet users are connecting to the same IP Address, but
using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address.
This IP Address is allocated by your ISP.
This address should be static, rather than dynamic, to make it easier for Internet users to
connect to your Servers.
However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your
Virtual Servers using a URL, instead of an IP Address.
