Wireless-N ADSL2+ Modem Router DGN2000 Reference Manual

The firewall protects your LAN against port scans and denial of service (DOS) attacks. This protection should be disabled only in special circumstances.

Responding to a Ping on an Internet WAN Port

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

Setting the MTU Size

The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs you might need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.

Disabling the SIP ALG

The Session Initiation Protocol (SIP) Application Level Gateway (ALG) is enabled by default to optimize VoIP phone calls that use the SIP. The Disable SIP ALG check box allows you to disable the SIP ALG. Disabling the SIP ALG might be useful when running certain applications.

Configuring LAN IP Settings

The LAN IP Setup screen allows configuration of LAN IP services such as DHCP and RIP.

The modem router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a DHCP server. The modem router’s default LAN IP configuration is as follows:

LAN IP address. 192.168.0.1

Subnet mask. 255.255.255.0

These addresses are part of the Internet Engineering Task Force (IETF)–designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes by opening the LAN IP Setup menu.
