Responding To Ping On Internet Wan Port; Setting The Mtu Size - NETGEAR RangeMax WPN824 Reference Manual

Reference Manual for the RangeMax Wireless Router WPN824
Responding to a Ping on the 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. Do not check this 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,
1492 Bytes for PPPoE connections, or 1436 for PPTP connections. For some ISPs you may need to
reduce the MTU. However, this is rarely required, and should not be done unless you are sure it is
necessary for your ISP connection.
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.
