Authentication Type
: The default is set to “
Auto Select
”, which allows
“
Open System
” or “
Shared Key
” authentication to be used. Select
“
Shared Key
” if you only want to use “
Shared Key
” authentication (the
sender and recipient both must use the same WEP key for
authentication).
h
Fragmentation Threshold:
This value specifies the maximum size for a
packet before data is fragmented into multiple packets. You should
leave this value in the 256 to 2346 range. In most cases, it should
remain as its default value of 2346. Setting the Fragmentation
Threshold too low may result in poor network performance.
h
RTS Threshold:
You can set RTS Threshold value in this field, the valid
range should be 256-2347 and default value is 2347. If a network
packet is smaller than the preset RTS threshold size, the RTS/CTS
mechanism will not be enabled.
h
DTIM Interval:
The “
DTIM Interval
” indicates the interval of the
Delivery Traffic Indication Message, you can set this value in the
20-1000 range, and the default value is 100.
h
Transmit Rate:
Transmit rate indicates the transmission speed of
wireless LAN access .The default setting is “
Auto
” and you can set this
value between 1 – 54Mbps range.
h
802.11g Protection:
Using 802.11b and 802.11g mixed mode may
result in poor network performance. By enabling the 802.11 protection,
it will improve performance of 802.11g devices in your wireless
network.
h
Preamble Type:
"
Short Preamble
" is suitable for heavy traffic wireless
network which will significantly increase the throughput performance at
higher data rates. While "
Long Preamble
" provides more
communication reliability and will ensure maximum stability of the
connection; the default setting is “
Long Preamble
”.
h
AP Isolation:
Create separate virtual networks for your wireless
network. After enable this function, every wireless client will in its own
virtual network and can not access each other. If many users access
your wireless network frequently, you should enable this function.
3.5.2 Secondary AP Setup

defaults as Disable, when you enable it, this function will
look very similar to the Primary AP Setup. However, please do name the SSID

differently from the Primary SSID; otherwise, you might not be able to direct your
Wireless Adapter to connect to it.
3.5.3 AP Sharing Technique
By default, the primary AP and the secondary AP are sharing under same IP
Range; as “
AP Sharing Technique
” is Enable.
You can also “
Disable
” the AP Sharing Technique to have the Primary AP and the
Secondary AP use different sets of IP range. You will then be asking to set
another IP segment for your secondary SSID.

IP Address will be use as the Default Gateway IP address for your computer (Router’s
factory setting for IP Address/Subnet Mask is
192.168.1.1
/
225.225.225.0
)
h
IP Address: This is the IP address of your Router in the Local Network
h
Subnet Mask: This is the Subnet Mask of your Router in Local Network.
“
LAN Setup
” also provides you with the management ability for “
DHCP server
”.
h
DHCP Server Status: to enable or disable your Router’s DHCP server
function (Factory default as Enable)
h

3.7 RNX-GX4’s Advance Usage -
Applications and Gaming Page
This section provides functions which you can utilize to help optimize the internet
speed for some of the games and applications.
3.7.1 Virtual Service
The Virtual Service of RNX-GX4 provides port mapping from LAN to WAN where
all outside visits to this port will be redirect to the designated computer within this
service. You can set different protocol and for both the external and internal port
range depending on your needs.
Dynamic Host Configuration Protocol
(
DHCP
) server will automatically assign an IP address for all
computers that connect to it. Internet protocol (TCP/IP) includes IP address, subnet mask, Gateway,
DNS server, and other information. It is very complicated to set TCP/IP for all computers within the
Local Network, therefore many Routers will set to enable DHCP server as default. When enable
DHCP server, your computer will also need to set “Obtain an IP address automatically” and “Obtain
DNS server address automatically”.
If you changed “LAN IP Address” in the Router, you will need to use the new set of IP address to log
back in to the Router, and all of your computers’ IP addresses will need to change, in order to access
internet.

Description
: This is for your reference of the name of the Virtual Server
you will be using. You can type in your preferences.
h
Internal Host IP Address
:
Internal Host IP Address refers to the
internal computer’s IP address that you want to use. This internal
computer’s IP address preferable to be manually set so you won’t have
to change every time you restart the computer.
h
Protocol
: Protocols are the protocol type that you want to set for your
internal host. For example, if you have a web server, you can set the
protocol as HTTP.
h
External Port
: This is referring to the port which broadcast by your
RNX-GX4. You can enter a range of the port for this setting. For
example, 80~90.
h
Internal Port
: This is referring to the specific service TCP/UDP port of
your internal host. For example, if you have a web server IP as
192.168.1.110, internal port 80, then you can set this virtual service like
the picture above.
IMPORTANT
:
If you set your port as 8080, you will need to change the 8080 port in the “
Remote Management
Port
” under “
Firewall
” of “
Security Management
” to the other port. Otherwise, this may cause a
conflict between the Virtual Service and Remote Management.
3.7.2 DMZ
Some programs require having multiple port connection, such as Internet Gaming
programs, Video Conferencing programs, and Internet Phones. Due to the firewall
limitation, these programs will not be able to work under virtual service. The
purpose of a DMZ is to add an additional layer of security to your Local Area
Network (LAN); an external attacker only has access to equipment in the DMZ,
rather than the whole of the network.
