WAN Setup
You can configure a DMZ (demilitarized zone) server, change the maximum transmit unit 
(MTU) size, and enable the Trek to respond to a ping on the WAN (Internet) port. The Trek 
does not support a VPN endpoint, but it allows traffic from VPN endpoints to pass through.
To change the WAN settings:
1.  Launch your browser from a computer or wireless device that is connected\
 to the T
 rek.
2.  Enter  www
 .routerlogin.net or  www.routerlogin.com in the web browser address bar.
The login screen displays.
3.  Enter the T
 rek user name and password.
The user name is  admin. 
 The default password is password . The user name and 
password are case-sensitive.
4.  Click the  OK button.
The BASIC Home screen displays.
5.  Select  ADV
 ANCED > Setup > WAN Setup.
6. Enter the following settings: 
• 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. By  default, this check box is cleared.
• Default DMZ Server . 
 A demilitarized zone (DMZ) server can be helpful when you 
play online games and use videoconferencing. Be careful when you use thi\
s feature 
because it makes the firewall security less effective. For more information, see 
Default DMZ Server on page  55.

•Respond to Ping on Internet Port. If you want the Trek to respond to a ping from the 
Internet, select this check box. By default, this check box is cleared. Use this feature 
only as a diagnostic tool because it allows your Trek 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 change is rarely required. Do not make 
this change unless you are sure that it is necessary for your ISP connection. For more 
information, see 
Change the MTU Size on page 57.
•NAT Filtering. Network Address Translation (NAT) determines how the Trek 
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. By default, 
the Secured radio button is selected.
-Open NAT provides a much less secured firewall, but allows almost all Internet 
applications to function.
•Disable SIP ALG. Some Voice over IP (VoIP) applications do not function well with 
the Session Initiation Protocol (SIP) Application Layer Gateway (ALG). Selecting the 
check box to turn off the SIP ALG might enable connected VoIP devices to create and 
accept a VoIP call through the Trek. By default, this check box is cleared.
•Disable IGMP Proxying. IGMP proxying allows computers on the LAN to receive the 
multicast traffic they are subscribed to from the Internet. By default, this check box is 
selected, and the IGMP proxy is disabled, preventing multicast traffic from the Internet 
to the LAN. Clear the Disable IGMP Proxying check box to allow multicast traffic 
from the Internet to the LAN.
•VPN Passthrough. The Trek supports VPN passthrough for IPSec, PPTP, and L2TP.
-IPSec Passthrough. To enable or disable IPSec passthrough, select the Enable 
or Disabled radio button.
-PPTP Passthrough. To enable or disable PPTP passthrough, select the Enable 
or Disabled radio button.
-L2TP Passthrough. To enable or disable L2TP passthrough, select the Enable 
or Disabled radio button.
7. Click the Apply button.
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 Trek is programmed to recognize some of these applications and to work 
correctly with them, but other applications 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.

Trek N300 Travel Router and Range Extender PR2000 
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 Trek discards incoming traffic from the Internet unless the traffic is a response to one of  your local computers. Instead of discarding this traf
 fic, you can forward it to one computer on 
your network. This computer is called the default DMZ server.
To set up a default DMZ server: 
1.  Launch your browser from a computer or wireless device that is connected\
 to the T
 rek.
2.  Enter  www
 .routerlogin.net or  www.routerlogin.com in the web browser address bar.
The login screen displays.
3.  Enter the T
 rek user name and password.
The user name is  admin. 
 The default password is password . The user name and 
password are case-sensitive.
4.  Click the  OK button.
The BASIC Home screen displays.
5.  Select  ADV
 ANCED > Setup > WAN Setup.
6. Select the  Default DMZ Server check box.
7.  T
ype the IP address.
8.  Click the  Apply button.

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 any device in the data path has a lower MTU 
setting than the other devices, the data packets must 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, and changing 
the value might fix one problem but cause another.
WARNING:
An incorrect MTU setting can cause Internet communication 
problems such as the inability to access certain websites, frames 
within websites, secure login pages, or FTP or POP servers.
Leave the MTU unchanged unless one of these situations occurs:
•You have problems connecting to your ISP or other Internet service, and technical 
support of either the ISP or NETGEAR recommends changing the MTU setting. These 
web-based applications might require an MTU change:
-A secure website that does not open, or displays only part of a web page
-Yahoo email
-MSN portal
-America Online’s DSL service
•You use VPN and have severe performance problems.
•You used a program to optimize MTU for performance reasons, and now you have 
connectivity or performance problems.
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 3.  Common MTU sizes 
MTUApplication
1500The largest Ethernet packet size. This value is the typical setting for non-PPPoE, non-VPN 
connections, and is the default value for NETGEAR Treks, adapters, and switches.
1492Used in PPPoE environments.
1472Maximum size to use for pinging. (Larger packets are fragmented.)
1468Used in some DHCP environments.
1460Usable by AOL if you do not have large email attachments, for example.

The Trek is shipped preconfigured to use private IP addresses on the LAN side\
 and to act as 
a DHCP server. The Trek’s default LAN IP configuration includes the following settings:
• LAN IP address . 192.168.168.1
• 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 requires t\
he use of a dif
 ferent IP 
addressing scheme, make the changes in the LAN Setup screen.
Note: If you change the LAN IP address of the Trek while connected 
through the browser, you are disconnected. You must open a new 
connection to the new IP address and log in again.
To change the LAN settings:
1. Launch your browser from a computer or wireless device that is connected\
 to the T
 rek.
2.  Enter  www
 .routerlogin.net  or www.routerlogin.com in the web browser address bar.
The login screen displays.
3.  Enter the T
 rek user name and password.
The user name is  admin. 
 The default password is password. The user name and 
password are case-sensitive.
4.  Click the  OK button.
The BASIC Home screen displays.
5.  Select  ADV
 ANCED > Setup > LAN Setup .
6. Enter the following settings: 
• IP Address. 
 The LAN IP address of the Trek (by default,  192.168.168.1).

•IP Subnet Mask. The LAN subnet mask of the Trek (by default, 255.255.255.0). 
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. Router Information Protocol (RIP) enables a router to exchange 
routing information with other routers. This setting controls how the Trek sends and 
receives RIP packets. Both is the default setting. With the Both or Out Only setting, 
the Trek broadcasts its routing table periodically. With the Both or In Only setting, the 
Trek incorporates the RIP information that it receives.
•RIP Version. This setting controls the format and the broadcasting method of the RIP 
packets that the Trek sends. It recognizes both formats when receiving. By default, 
the RIP function is disabled. Four RIP versions exist:
-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.
7. To set your computers’ IP addresses manually, clear the Use Router as DHCP Server 
check box.
NETGEAR recommends that you do not do this. For more information, see Use the Trek 
as a DHCP Server on page 60.
8. To reserve an IP address for a computer or device on the LAN, in the Address Reservation 
section, click the Add button.
For more information, see Set Up Address Reservation on page 62.
9. Click the Apply button.
Use the Trek as a DHCP Server
By default, the Trek functions as a DHCP server, allowing it to assign IP, DNS server, and 
default gateway addresses to all computers connected to the Trek’s LAN. The assigned 
default gateway address is the LAN IP address of the Trek. The Trek 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 Trek are satisfactory. 
You can specify the pool of IP addresses for assignment by setting the starting IP address 
and ending IP address. These addresses must be part of the same IP address subnet as the 
Trek’s LAN IP address. Using the default addressing scheme, define a range between 
192.168.168.2 and 192.168.168.200, although you might want to save part of the range for 
devices with fixed addresses.
The Trek delivers the following parameters to any LAN device that requests DHCP:
•An IP address from the range that you defined
