N300 Wireless ADSL2+ Modem Router DGN2200Mv2
Description
When enabled, this feature will allow a PPPoE client on a local PC to
connect to a remote PPPoE server with the gateway acting as a relay
agent.
The SPI (Stateful Packet Inspection) firewall protects your LAN against
denial of service attacks. This should only be disabled in special
circumstances.
See Default DMZ Server
If you want the wireless modem router to respond to a ping from the
Internet, select the Respond to Ping on Internet Port check box. This
should be used only as a diagnostic tool, since it allows your wireless
modem router to be discovered. Do not select this check box unless you
have a specific reason to do so.
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.
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.
