2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login window opens.
3. Enter the router user name and password.
The user name is admin.
The user name and password are case-sensitive.
The BASIC Home page displays.
4. Select ADV
ANCED > Setup > WAN Setup.
The following settings display:
• Disable Port Scan and DoS Protection. DoS protection protects your LAN against
denial of service attacks such as Syn flood, Smurf
Attack, Ping of Death, and many
others. Select this check box only in special circumstances.
• Default DMZ Server.
This feature is sometimes helpful when you are playing online
games or videoconferencing, but it makes the firewall security less effective. See Set
Up a Default DMZ Server on page 108.
• Respond to Ping on Internet Port. This
feature allows your router to be discovered.
Use this feature only as a diagnostic tool or for a specific reason.
• Disable IGMP Proxying. IGMP proxying allows a computer on the local area network
(LAN) to receive the multicast traf
fic it is interested in from the Internet. If you do not
need this feature, you can select this check box to disable it.
• MTU Size (in bytes).
The normal MTU (maximum transmit unit) value for most
Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Change the
MTU only if you are sure that it is necessary for your ISP connection. See Change the
MTU Size on page 38.
• NA
T Filtering. Network Address Translation (NAT) determines how the router
processes inbound traffic. Secured NAT protects computers on the LAN from attacks
from the Internet, but might prevent some Internet games, point-to-point applications,
or multimedia applications from working. Open NAT provides a much less secured
firewall, but allows almost all Internet applications to work.
• Disable SIP
ALG. Some voice or video communication applications do not work well
with SIP ALG. Disabling SIP ALG might help your voice or video applications to
create or accept a call through the router.
