Responding to a Ping on the Internet (WAN) Port
If you want the 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
router to be discovered by Internet scanners. Do not select this check box unless you have a
specific reason to do so, such as when troubleshooting your connection.
Setting the MTU Size
The normal MTU value for most Ethernet networks is 1500 bytes, 1492 bytes for PPPoE
connections, or 1450 for PPTP connections. For some ISPs, you might need to reduce the
MTU size, but this is rarely required and should not be done unless you are sure it is
necessary for your ISP connection. For more information, see
page 73.
To change the MTU size:
1.
In the MTU Size field, enter a new size between 64 and 1500.
2.
Click Apply to save the new configuration.
Configuring NAT Filtering
Network Address Translation (NAT) determines how the router processes inbound traffic.
Secured NAT provides a secured firewall to protect the computers on the LAN from attacks
from the Internet, but might prevent some Internet games, point-to-point applications, or
multimedia applications from functioning. Open NAT provides a much less secured firewall,
but allows almost all Internet applications to function. For more information about NAT, see
How Your Computer Accesses a Remote Computer through Your Router
To change the NAT option:
1.
In the NAT Filtering area, select either the Secured or the Open radio button.
2.
Click Apply to save the new configuration.

Internet access, and you do not need to configure additional static routes. You must
