Mobile LTE Broadband 11n Wireless Router MBR1516 WAN Setup The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the maximum transmit unit (MTU) size, and enable the router to respond to a ping on the WAN (Internet) port. Select ADVANCED > Setup > WAN Setup to view the following screen: • 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, Teardrop Attack, UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. This should be disabled only in special circumstances. • Default DMZ Server. This feature is sometimes helpful when you are playing online games or videoconferencing. Be careful when using this feature because it makes the firewall security less effective. See Default DMZ Server on page 39 for more details. • Respond to Ping on Internet Port. If you want the router to respond to a ping from the Internet, select this check box. Use this only as a diagnostic tool because it allows your router to be discovered. Do not select this check box unless you have a specific reason. • MTU Size (in bytes). 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. This is rarely required, and should not be done unless you are sure it is necessary for your ISP connection. See Change the MTU Size on page 39. • 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. • Disable SIP ALG. Some VoIP applications do not work well with the SIP ALG. Selecting this check box to turn off the SIP ALG helps your VoIP devices create and accept calls through the router. NETGEAR genie ADVANCED Home 38

WAN Setup
The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the
maximum transmit unit (MTU) size, and enable the router to respond to a ping on the WAN
(Internet) port. Select
ADVANCED > Setup > WAN Setup
to view the following screen:
•
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, Teardrop Attack,
UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. This should be
disabled only in special circumstances.
•
Default DMZ Server
. This feature is sometimes helpful when you are playing online
games or videoconferencing. Be careful when using this feature because it makes the
firewall security less effective. See
Default DMZ Server
on page 39 for more details.
•
Respond to Ping on Internet Port
. If you want the router to respond to a ping from the
Internet, select this check box. Use this only as a diagnostic tool because it allows your
router to be discovered. Do not select this check box unless you have a specific reason.
•
MTU Size (in bytes)
. 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. This is rarely required, and should not be done unless you are
sure it is necessary for your ISP connection. See
Change the MTU Size
on page 39.
•
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.
•
Disable SIP ALG
. Some VoIP applications do not work well with the SIP ALG. Selecting
this check box to turn off the SIP ALG helps your VoIP devices create and accept calls
through the router.
