Figure 7-2: WAN Setup menu.

To assign a computer or server to be a Default DMZ server, follow these steps:

1.Click WAN Setup link on the Advanced section of the main menu.

2.Type the IP address for that server. To remove the default DMZ server, replace the IP address numbers with all zeros.

3.Click Apply.

Respond to Ping on Internet WAN Port

If you want the router to respond to a 'ping' from the Internet, click the ‘Respond to Ping on Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your router to be discovered. Don't check this box unless you have a specific reason to do so.

Setting the MTU Size

The default MTU size is usually fine. The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes. For some ISPs, particularly some using PPPoE, you may need to reduce the MTU. This should not be done unless you are sure it is necessary by your ISP.

Any packets sent through the router that are larger than the configured MTU size will be repackaged into smaller packets to meet the MTU requirement. To change the MTU size:

1.Under MTU Size, enter a new size between 64 and 1500.

2.Click Apply to save the new configuration.
