Reference Manual for the ADSL Modem Wireless Router DG834GSP
7-4 Advanced Configuration
v1.0, June 2007
Enable PPPoE-Relay
When enabled, this feature allows a PPPoE client on a local PC to a remote PPPoE server with the
gateway acting as a relay agent.
Disable Port Scan and DOS Protection
The Firewall protects your LAN against Port Scans and Denial of Service (DOS) attacks. This
should be disabled only in special circumstances.
Respond to Ping on 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 only be used as a diagnostic tool, since it allows
your modem router to be discovered. Do not select this box unless you have a specific reason to do
so.
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 may 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.
Configuring LAN IP Settings
The LAN IP Setup menu allows configuration of LAN IP services such as DHCP and RIP. These
features can be found under the Advanced heading in the Main Menu of the browser interface.
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:
• LAN IP addresses—10.1.1.1
• Subnet mask—255.255.255.0
