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 i\
t makes the 
firewall security less effective. See the following section,  Default DMZ Server, 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 setting only as a diagnostic t\
ool because it allows 
your router to be discovered. Do not select this check box unless you ha\
ve 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. For some IS\
Ps, 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  35.
•      NA
T 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 game\
s, point-to-point  
						

							Genie Advanced Home
35  R6300 WiFi Router 802.11ac Dual Band Gigabit
applications, or multimedia applications from functioning. Open NAT provides a much 
less secured firewall, but allows almost all Internet applications to function. 
Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and 
videoconferencing applications that are incompatible with Network Address Translation 
(NAT). The router is programmed to recognize some of these applications and to work 
correctly with them, but there are other applications that might not function well. In some 
cases, one local computer can run the application correctly if that computer’s IP address is 
entered as the default DMZ server.
WARNING!
DMZ servers pose a security risk. A computer designated as the 
default DMZ server loses much of the protection of the firewall 
and is exposed to exploits from the Internet. If compromised, the 
DMZ server computer can be used to attack other computers on 
your network.
The router usually detects and discards Incoming traffic from the Internet that is not a 
response to one of your local computers or a service that you have configured in the Port 
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have the router 
forward the traffic to one computer on your network. This computer is called the default DMZ 
server.
To set up a default DMZ server: 
1. On the WAN Setup screen, select the Default DMZ Server check box.
2. Type the IP address.
3. Click Apply.
Change the MTU Size
The Maximum Transmission Unit (MTU) is the largest data packet a network device 
transmits. When one network device communicates across the Internet with another, the data 
packets travel through many devices along the way. If a device in the data path has a lower 
MTU setting than the other devices, the data packets have to be split or “fragmented” to 
accommodate the device with the smallest MTU. 
The best MTU setting for NETGEAR equipment is often just the default value. In some 
situations, changing the value fixes one problem but causes another. Leave the MTU 
unchanged unless one of these situations occurs:
•     You have problems connecting to your ISP or other Internet service, and the technical 
support of either the ISP or NETGEAR recommends changing the MTU setting. These 
web-based applications might require an MTU change:

•      Y
ou use VPN and have severe performance problems.
•     Y
ou used a program to optimize MTU for performance reasons, and now you h\

Note:   An incorrect MTU setting can cause Internet communication 
problems. For instance, you might not be able to access certain 
websites, frames within websites, secure login pages, or FTP or 
POP servers.
If you suspect an MTU problem, a common solution is to change the MTU to\
 1400. If you are 
willing to experiment, you can gradually reduce the MTU from the maximum\
 value of 1500 
until the problem goes away
 . The following table describes common MTU sizes and 
applications. 
Table 2.  Common MTU Sizes   
MTUApplication
1500 The largest Ethernet packet size and the default value. This setting is typical for 
connections that do not use PPPoE or VPN, and is the default value for N\
ETGEAR 
routers, adapters, and switches.
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)
1468 Used in some DHCP environments.
1460 Usable by AOL if you do not have large email attachments, for example.
1436 Used in PPTP environments or with VPN.

LAN Setup
The LAN Setup screen allows configuration of LAN IP services such as Dyn\
amic Host 
Configuration Protocol (DHCP) and Routing Information Protocol (RIP)\
.
The router is shipped preconfigured to use private IP addresses on the L\
AN side and to act  as a DHCP server
 . The router’s default LAN IP configuration is:
•     LAN IP address. 192.168.1.1
•     Subnet mask.  255.255.255.0
These addresses are part of the designated private address range for use\
 in private networks  and are suitable for most applications. If your network requires a dif
 ferent IP addressing 
scheme, you can change these settings in the LAN Setup screen.
To change the LAN settings:
Note:   If you change the LAN IP address of the router while connected 
through the browser, you will be disconnected. You will have to open 
a new connection to the new IP address and log in again.
1.  Select  Advanced > Setup > LAN Setup to display the following screen:
2. Enter the settings that you want to customize. These settings are described in the following 
section,  LAN Setup Screen Settings.
3.  Click  Apply to save your changes.

LAN Setup Screen Settings
LAN TCP/IP Setup
•     IP Address. The LAN IP address of the router.
•     IP Subnet Mask. The LAN subnet mask of the router. Combined with the IP address, the 
IP subnet mask allows a device to know which other addresses are local to it, and which 
have to be reached through a gateway or router.
•     RIP Direction. Router Information Protocol (RIP) allows a router to exchange routing 
information with other routers. This setting controls how the router sends and receives 
RIP packets. Both is the default setting. With the Both or Out Only setting, the router 
broadcasts its routing table periodically. With the Both or In Only setting, the router 
incorporates the RIP information that it receives.
•     RIP Version. This setting controls the format and the broadcasting method of the RIP 
packets that the router sends. It recognizes both formats when receiving. By default, the 
RIP function is disabled. 
RIP-1 is universally supported. It is adequate for most networks, unless you have an 
unusual network setup. 
RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 
format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting.
Use Router as a DHCP Server 
This check box is usually selected so that the router functions as a Dynamic Host 
Configuration Protocol (DHCP) server. 
•     Starting IP Address. Specify the start of the range for the pool of IP addresses in the 
same subnet as the router.
•     Ending IP Address. Specify the end of the range for the pool of IP addresses in the 
same subnet as the router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer receives 
the same IP address each time it accesses the router’s DHCP server. Assign reserved IP 
addresses to servers that require permanent IP settings. 
Use the Router as a DHCP Server
By default, the router acts as a DHCP server. The router assigns IP, DNS server, and default 
gateway addresses to all computers connected to the LAN. The assigned default gateway 
address is the LAN address of the router. The router assigns IP addresses to the attached 
computers from a pool of addresses specified in this screen. Each pool address is tested 
before it is assigned to avoid duplicate addresses on the LAN. For most applications, the 
default DHCP and TCP/IP settings of the router are satisfactory.  
						

							Genie Advanced Home
39  R6300 WiFi Router 802.11ac Dual Band Gigabit
You can specify the pool of IP addresses to be assigned by setting the starting IP address 
and ending IP address. These addresses should be part of the same IP address subnet as 
the router’s LAN IP address. Using the default addressing scheme, define a range between 
192.168.1.2 and 192.168.1.254, although you might want to save part of the range for 
devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
•     An IP address from the range you have defined
•     Subnet mask
•     Gateway IP address (the router’s LAN IP address)
•     Primary DNS server (if you entered a primary DNS address in the Internet Setup screen; 
otherwise, the router’s LAN IP address)
•     Secondary DNS server (if you entered a secondary DNS address in the Internet Setup 
screen)
To use another device on your network as the DHCP server, or to specify the network 
settings of all of your computers, clear the Use Router as DHCP Server check box and click 
Apply. Otherwise, leave this check box selected. If this service is not enabled and no other 
DHCP server is available on your network, set your computers’ IP addresses manually or 
they will not be able to access the router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer always 
receives the same IP address each time it accesses the router’s DHCP server. Reserved IP 
addresses should be assigned to computers or servers that require permanent IP settings. 
To reserve an IP address: 
1. In the Address Reservation section of the screen, click the Add button. 
2. In the IP Address field, type the IP address to assign to the computer or server. (Choose an 
IP address from the router’s LAN subnet, such as 192.168.1.x.) 
3. Type the MAC address of the computer or server.
Tip:  If the computer is already on your network, you can copy its MAC 
address from the Attached Devices screen and paste it here.
4. Click Apply to enter the reserved address into the table. 
The reserved address is not assigned until the next time the computer contacts the 
router’s DHCP server. Reboot the computer, or access its IP configuration and force a 
DHCP release and renew.
To edit or delete a reserved address entry, select the radio button next to the reserved 
address you want to edit or delete. Then click Edit or Delete.

Quality of Service (QoS) Setup
QoS is an advanced feature that can be used to prioritize some types of \
traffic ahead of 
others. The R6300 WiFi Router can provide QoS prioritization over the wireless l\
ink and on 
the Internet connection. To configure QoS, use the QoS Setup screen. 
Select 
Advanced > Setup > QoS Setup to display the following screen: 
Enable WMM QoS for Wireless Multimedia Applications
The R6300 WiFi Router supports Wi-Fi Multimedia Quality of Service (WMM\
 QoS) to 
prioritize wireless voice and video traffic over the wireless link. WMM QoS provides 
prioritization of wireless data packets from different applications based on four access 
categories: voice, video, best effort, and background. For an application to receive the 
benefits of WMM QoS, both it and the client running that application hav\
e to have WMM 
enabled. Legacy applications that do not support WMM and applications th\
at do not require 
QoS, are assigned to the best effort category, which receives a lower priority than voice and 
video. 
WMM QoS is enabled by default. You can disable it in the QoS Setup screen by clearing the 
Enable WMM check box and clicking  Apply.
Set Up QoS for Internet Access
You can give prioritized Internet access to the following types of traffic:
•     Specific applications
•     Specific online games
•     Individual Ethernet LAN ports of the router
•     A specific device by MAC address
To specify prioritization of traffic, create a policy for the type of traffic and add the policy to the  QoS Policy table in the QoS Setup screen. For convenience, the QoS Polic\
y table lists many 
common applications and online games that can benefit from QoS handling.\
