   Chapter 4:   Customizing Your Network   Wireless-N 150 Router WNR612v2 User Manual 
Using the LAN IP Setup Options
The LAN Setup screen allows configuration of LAN IP services such as Dyn\
amic Host 
Configuration Protocol (DHCP) and Routing Information Protocol (RIP)\
. To configure LAN IP 
settings, select LAN Setup under Advanced in the main menu. The LAN Setup screen 
displays.
Configuring a Device Name
The device name is a user-friendly name for the router. This name is sho\
wn in the Network 
on Windows Vista and the Network Explorer on all Windows systems. The 
Device Name field 
cannot be blank. The default name is WNR612v2.
Configuring LAN TCP/IP Setup Parameters
These are advanced settings that you might configure if you are a networ\
k administrator and 
your network contains multiple routers. The router is shipped preconfigu\
red to use private IP 
addresses on the LAN side and to act as a DHCP server (see Using the Router as a DHCP 
Server on page   35).
Note:  If you change the LAN IP address of the router while connected 
through the browser, you will be disconnected. You must then open 
a new connection to the new IP address and log in again.
The router’s default LAN IP configuration is:
•     LAN IP address. 192.168.1.1 
						

							  Chapter 4:  Customizing Your Network     | 
   35 Wireless-N 150 Router WNR612v2 User Manual 
•     Subnet mask. 255.255.255.0
These addresses are part of the designated private address range for use in private networks 
and should be suitable for most applications. If your network has a requirement to use a 
different IP addressing scheme, you can make those changes in this screen.
The LAN IP settings are:
•     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 
must be reached through a gateway or router.
•     RIP Direction. RIP allows a router to exchange routing information with other routers. 
The RIP Direction selection controls how the router sends and receives RIP packets. 
Both is the default. 
-When set to Both or In Only, the router incorporates the RIP information that it 
receives. 
-When set to Both or Out Only, the router broadcasts its routing table periodically. 
•     RIP Version. This controls the format and the broadcasting method of the RIP packets 
sent by the router. (It recognizes both formats when receiving.) The default setting is 
Disabled. 
-RIP-1 is universally supported. RIP-1 is usually adequate unless you have an unusual 
network setup. 
-RIP-2B carries more information than RIP-1 and uses subnet broadcasting.
-RIP-2M carries more information than RIP-1 and uses multicasting.
Using the Router as a DHCP Server
By default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and 
default gateway addresses to all computers connected to the router’s 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.
Note:  For most applications, the default DHCP and TCP/IP settings of the 
router are satisfactory. Click the link to the online document 
TCP/IP 
Networking Basics  in Appendix B for an explanation of DHCP and 
information about how to assign IP addresses for your network.
To specify a pool of IP addresses to be assigned, set 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, you should define a range between 
192.168.1.2 and 192.168.1.254, although you might wish to save part of the range for 
devices with fixed addresses.

   Chapter 4:   Customizing Your Network   Wireless-N 150 Router WNR612v2 User Manual 
The router delivers the following parameters to any LAN device that requ\
ests 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 Basic S\
ettings screen; 
otherwise, the router’s LAN IP address)
•     Secondary DNS server (if you entered a secondary DNS address in the Bas\
ic Settings  screen)
To use another device on your network as the DHCP server, or to manually\
 specify the 
network settings of all of your computers, clear the  Use Router as DHCP Server check box. 
Otherwise, leave it selected. If this service is not selected and no oth\
er DHCP server is 
available on your network, you need to set your computers’ IP address\
es manually or they 
will not be able to access the router.
Using Address Reservation
When you specify a reserved IP address for a computer on the LAN, that c\
omputer 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 perman\
ent IP settings. 
To reserve an IP address: 
1.  Click  Add. 
2.  In the IP Address field, enter the IP address to assign to the computer or server. (Choo\
se 
an IP address from the router’s LAN subnet, such as  192.168.1.x.) 
3.  Enter the MAC address of the computer or server.
Tip:   If the computer is already present 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. 
Note:  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: 
1. 
Click the button next to the reserved address you want to edit or delete\
. 
2.  Click  Edit or  Delete.
Using a Dynamic DNS Service
If your Internet Service Provider (ISP) gave you a permanently assigne\
d IP address, you can 
register a domain name and have that name linked with your IP address by\
 public Domain 
Name Servers (DNS). However, if your Internet account uses a dynamical\
ly assigned IP 
address, you do not know in advance what your IP address will be, and th\
e address can 
change frequently. In this case, you can use a commercial Dynamic DNS se\
rvice, which 
allows you to register your domain to their IP address, and forwards tra\
ffic directed at your 
domain to your frequently changing IP address.
Note:  If your ISP assigns a private WAN IP address (such as 192.168.x.x 
or 10.x.x.x), the Dynamic DNS service will not work because private 
addresses are not routed on the Internet.
Your router contains a client that can connect to the Dynamic DNS servic\
e provided by 
DynDNS.org. You must first visit their website at  www.dyndns.org and obtain an account and 
host name, which you specify in the router. Then, whenever your ISP-assi\
gned IP address 
changes, your router automatically contacts the Dynamic DNS service prov\
ider, logs in to 
your account, and registers your new IP address. If your host name is ho\
stname, for 
example, you can reach your router at hostname.dyndns.org.
Select Dynamic DNS under Advanced in the main menu. The Dynamic DNS screen 
displays.

   Chapter 4:   Customizing Your Network  Wireless-N 150 Router WNR612v2 User Manual 
To configure for a Dynamic DNS service:
1. Register for an account with one of the Dynamic DNS service providers whose names 
appear in the Service Provider list. For example, for DynDNS.org, select 
www.dynDNS.org.
2. Select the Use a Dynamic DNS Service check box. 
3. Select the name of your Dynamic DNS service provider. 
4. Enter the host name (or domain name) that your Dynamic DNS service provider gave you.
5. Enter the user name for your Dynamic DNS account. This is the name that you use to log in 
to your account, not your host name.
6. Enter the password (or key) for your Dynamic DNS account. 
7. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can 
select the Use Wildcards check box to activate this feature. 
 
For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the same IP 
address as yourhost.dyndns.org.
8. Click Apply to save your configuration.
Configuring the WAN Setup Options
The WAN Setup options let you do the following:
•     Disable Port Scan and DoS Protection.
•     Configure a DMZ (demilitarized zone) server.
•     Enable the wireless router to respond to a ping on the WAN (Internet) port.
•     Disable IGMP Proxying – The IGMP Proxying function lets a LAN PC receive the 
multicast traffic is interested in from the Internet. You can click this check box to disable 
the function if you do not need it.
•     Change the Maximum Transmit Unit (MTU) size.
•     Disable DIP ALG – Some SIP applications have their own way to work around the NAT 
firewall issue, and the SIP ALG would conflict with those solutions. In most cases, you do 
not have to disable the SIP ALG. However, if your SIP applications cannot work with the 
router, you can disable the SIP ALG and try the applications again. Click the check box to 
disable SIP ALG.
•     Enable IPv6 Pass-Through – IPv6 pass-through is disabled by default. If you have IPv6 
capable devices in your configuration and would like to use IPv6 instead of IPv4, you can 
click this check box to enable IPv6 Pass)-Through.

Wireless-N 150 Router WNR612v2 User Manual 
Select WAN Setup
 under Advanced in the main menu. The WAN Setup screen displays. 
Disabling Port Scan and DOS Protection
The Port Scan and DOS Protection feature protects your network and compu\
ters against 
attacks and intrusions. A stateful packet firewall carefully inspects in\
coming traffic packets, 
looking for known exploits such as malformed, oversized, or out-of-seque\
nce packets. The 
Port Scan and Dos Protection feature should be disabled only in special \
circumstances, such 
as when you are troubleshooting application issues.
Setting Up a 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 Addres\
s Translation 
(NAT). The router is programmed to recognize some of these application\
s and to work 
correctly with them, but there are other applications that might not fun\
ction well. In some 
cases, one local computer can run the application correctly if that comp\
uter’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.
Incoming traffic from the Internet is usually discarded by the router un\
less the traffic is a 
response to one of your local computers or a service that you have confi\
gured in the Port 
Forwarding/Port Triggering screen. Instead of discarding this traffic, y\
ou can have it 
forwarded to one computer on your network. This computer is called the d\
efault DMZ server.
The WAN Setup screen lets you configure a default DMZ server. 
						

							40   |
   Chapter 4:   Customizing Your Network  Wireless-N 150 Router WNR612v2 User Manual 
To assign a computer or server to be a default DMZ server: 
1. Select the Default DMZ Server check box.
2. In the Default DMZ Server fields, enter the IP address for that computer or server.
3. Click Apply.
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.
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.
Disabling IGMP Proxying
The IGMP Proxying function lets a LAN PC receive the multicast traffic it is interested in from 
the Internet. If you do not need this function, you can click the Disable IGMP Proxying check 
box to disable this function.
Disabling SIP ALG
Some SIP applications have their own way to work around the NAT firewall issue, and the 
SIP ALG would conflict with those solutions. In most cases, you do not have to disable the 
SIP ALG. However, if your SIP applications cannot work with the router, you can disable the 
SIP ALG and try the applications again. To disable SIP ALG, click the Disable SIP ALG check 
box.
Enabling IPv6 Pass-Through
IPv6 pass-through is disabled by default. If you have IPv6-capable devices in your 
configuration and would like to use those devices instead of IPv4, you can click the Enable 
IPv6 Pass-Through check box to enable the IPv6 Pass-Through function.
