A750 Wireless Dual Band Gigabit Router JR6150
You can 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. The router
does not support a VPN endpoint, but it allows traffic from VPN endpoints to pass through.
To configure the WAN setup:
1. Log in to the router.
For more information, see Use NETGEAR genie after Installation on page 17.
2. Select ADVANCED > Setup > WAN Setup.
3. Enter the settings you want to customize:
•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
check box should be selected 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. For more information, see Default DMZ Server on
•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 capability 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 reduction is rarely required, and
should not be done unless you are sure that it is necessary for your ISP connection.
See Change the MTU Size on page 45.
•NAT Filtering. Network Address Translation (NAT) determines how the router
processes inbound traffic:
