View or Change WAN Settings
You can view or configure wide area network (WAN) settings for the Internet port. You can 
set up a DMZ (demilitarized zone) server, change the maximum transmit unit (MTU) size, and 
enable the router to respond to a ping to its WAN (Internet) port. 
To view or change the WAN settings:
1.  Launch a web browser from a computer or WiFi device that is connected to\
 the network.
2.  Enter  http://www...

•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. By default, 
the Secured radio button is selected.
-Open NAT provides a much less secured firewall, but...

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  detects and discards incoming traf
 fic from the Internet that is not a response to 
one of your local computers or a service that you have...

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 must be split or “fragmented” to 
accommodate the device with the smallest MTU. 
The best MTU...

5. In the MTU Size field, enter a value from 64 to 1500.
6.  Click the  Apply button.
Your change is saved.
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....

Specify the IP Addresses That the Router Assigns
By default, the router acts as a Dynamic Host Configuration Protocol (D\
HCP) 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. 
These addresses must be part of the same IP address subnet as the router\
’s LAN IP  address. Using the default...
