N300 Wireless Router Model JWNR2000Tv3
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 set up 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 are split or "fragmented" to accommodate the
device with the smallest MTU.
The best MTU setting for NETGEAR equipment is often 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:
•
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.
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.
