MTU

MTU size

MTU (Maximum Transmission Unit) value should only be changed if

advised to do so by Technical Support.

Enter a value between 1 and 1500.

This device will still auto-negotiate with the remote server, to set

the MTU size. The smaller of the 2 values (auto-negotiated, or en-

tered here) will be used.

•

For direct connections (not PPPoE or PPTP), the MTU used is

always 1500.

PC Database

The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It elimi-

nates the need to enter IP addresses. Also, you do not need to use fixed IP addresses on your

LAN.

PC Database Screen

An example

PC Database

screen is shown below.

Figure 48: PC Database

•

PCs which are "DHCP Clients" are automatically added to the database, and updated as

required.

•

By default, non-Server versions of Windows act as "DHCP Clients"; this setting is called

"Obtain an IP Address automatically".

•

The TW100-BRF114U uses the "Hardware Address" to identify each PC, not the name or

IP address. The "Hardware Address" can only change if you change the PC's network card

or adapter.

•

This system means you do NOT need to use Fixed (static) IP addresses on your LAN.

However, you can add PCs using Fixed (static) IP Addresses to the PC database if re-

quired.

IP Address

Select the appropriate option:

•

Automatic

- The PC is set to be a DHCP client (Windows: "Ob-

tain an IP address automatically"). The TW100-BRF114U will

allocate an IP address to this PC when requested to do so. The IP

address could change, but normally won't.

•

DCHP Client - Reserved IP Address

- Select this if the PC is set

to be a DCHP client, and you wish to guarantee that the TW100-

BRF114U will always allocate the same IP Address to this PC.

Enter the required IP address. Only the last field is required; the

other fields must match the Broadband Router's IP address.

•

Fixed IP Address

- Select this if the PC is using a Fixed (Static)

IP address. Enter the IP address allocated to the PC. (The PC must

be configured to use this IP address.)
