Chapter 1 The use of CMS
Before configuring the router, please ensure that your computer is installed necessary
softwares(for example: Windows 95/98/ME/NT2000/XP), and configure the netwok in
reason. If you don’t know how to configure network, please read the setting explanation
of next section ”Configure network”. If you have already configured network correctly,
you can leap over next section and refer to “Configuration guide” directly.
Note:
1) This configuration method(configure router by Web page layout) is suitable for primary technical
personnel, but we recommend telnet mode to configure router for intermediate or senior technical
personnel. You should avoid by all means using web and telnet at one time to config router.
2) When you use web to config 1705, You should renovate the page layout after configuring 1705
completely in order to show the correct result.
3) If you use web to config 1705, we suggest that you ues Microsoft IE browser 6.0 or high-edition,
and use 1024*768 screen area.
1.1 The network setting
The default interface of 1705 is TP2, and the default IP address of TP2 is 192.168.2.1,
the default subnet mask is 255.255.255.0. These parameters can be altered for need,
and they are default value in the following character. The material step for setting
network is shown as following (take example for Windows 2000):
Step 1: Connect your computer to the fast Ethernet port TP2 of 1705 router.
Step 2: Setting the IP address of this computer.
(1) Beginning－>control panel－>network and dialing connection
(2) Use the right key to click”network connections”, then click”property”menu.
(3) Pitch on”Internet protocol(TCP/IP)”. The figure is following:

(4) Click”property”keystoke and set IP address of the computer.
(5) In the dialog box of “Internet protocol(TCP/IP) property”, pitch on”use the
following IP address”. Infilling 192.168.2.xxx in”IP address”(the range of xxx is
2~254). Infilling 255.255.255.0 in”subnet mask”. Infilling 192.168.2.1 in”default
gateway”(that is the default IP address of 1705 router).
Note:
Because the default IP address of 1705 router is 192.168.2.1, xxx can’t be filled in 1.
As the following figure show:

It is similar with WAN port setting of chapter 1.3.1, but it can configure one or two
ports. You can refer to chapter 1.3.1 to configure the parameter.
If you use two ports to connect Internet, you should configure the parameter of
ISP and bandwidth.
Note: ISP chosen is used to make the configuration high-efficient in mutiplex line. We provide a
file named “isp_db” in order to achieve the configuration result( it is in router when leave
factory ). But this file isn’t necessary. If the system show the following page when you
logging on router:
It is show that the file named “isp_db” is lost. You can do follow this: Advanced
setting->Mutiplex line, to upgrade this file. ( Refer to chapter 1.5.1)

1705Router Web Configuration Manual
Secondary IP address, subnet mask: fill in the IP address and subnet mask.
Note:
If the system shows the following information:
It is warning: you are configuring the router through this port, and you couldn’t alter this IP address. If you
click “apply” button to alter this IP address, system will disconnect with Web and you will not configure the
router.
1.4.3 NAT Configuration
What is called NAT, that is Network Address Translation. Its essence is that alter the
source IP address of data-packets which pass through router, in order to make more
users share one public ip address, or open Web service and FTP service in LAN.
The configuration page layout is following:
There are two parts:
 Connection Settings:
 Max-entries: The value is used to set the max-entries for NAT mapping. ( In
order to prevent virus, usually the value is 300. It depend on using situation
- 11 -

1705Router Web Configuration Manual
of computer. If you download something by BT, the value is more. There are
200 PC in one net-bar, about 600 is enough.)
 Max-entries(per host): It is used to set max-entries for each IP.
 Address Mapping Setting:
The configuration make all users in LAN share one public IP address. They can
browse Internet at one time, but the users which are in Internet can’t call users in
LAN.
There are three steps to configure router in this setting.
First: Ensure the port of LAN, click links of access list to enter configuration page
layout:
It shows the final configuration result. Click “add” to add new list, “Edit” is used to
edit the current list. “Del” is used to delete list. If there are some lists, you can
click “Up” and “Dn” to move.

IP Subnet――one IP address and one subnet mask.
Src port: it is only used in TCP or UDP protocol.
Any
——all ports.
=,>,<,!=(unequal to )——limit the value of some port.
Range——range of one section port.
Typically you should select IP range in source IP to fill in PC IP of LAN, or select
IP Subnet to fill in the net-segment of LAN.
Destination IP: idem.
Destination Port: idem.
Typically the destination IP should select Any.
Time Range: Choose the efficient time range of this list. Usually we choose
always.
Click “apply” to make the configuration effective, “back” is cancel.
Third: Enable NAT function.
In the following page layout:
Select “Enable” and click “Apply” to make the list effective.

It includes the following submenu: “Mutiplex Line”, “Port Mapping”, “Special NAT”,
“Firewall”, “Default Route”, “Static Route”, “DDNS Settings”, “VPN Settings”. Advanced
settings can help you finish some advanced function for router.
- 14 -

1705Router Web Configuration Manual
1.5.1 Multiplex Line
A. There are more WAN ports in router, and they can connect Internet at one time.
You could design the flux control of port according to bandwidth of every line.
You can use “ WAN Flux Setting” to achieve the control.
Enable: Enable or Disable.
Bandwidth: fill in the bandwidth provided by ISP.
Click “Apply” to make the configuration effective.
B. ISP DB Update. When system is warning that there is no file named “isp_db”, you
should click ”browse” to find this file, then click “Upgrade”, and reboot the router to
make the file effective.
C. “Policy Route Setting” is used to separate LAN into several parts, in order to make
every WAN port communicate with Internet normally.
For example: TP0 and TP1 are WAN ports, the address range of LAN is
192.168.2.100~192.168.2.200. We hope that separate LAN into two part:
192.168.2.100~192.168.2.150 browse Internet through TP0, and
192.168.2.151~192.168.2.200 browse Internet through TP1. Click “add” button:
LAN Group: fill in one number to mark different LAN net-segment.
LAN IP Address Range: fill in the address range in LAN.
Out Port & Sec. Out Port: select the WAN port to transmit the LAN's packets. (Also
can select another port as backup).
- 15 -

1705Router Web Configuration Manual
1.5.2 Port Mapping
Port mapping is one of NAT. It is used to mapping the IP address in LAN or TCP/UDP
port of one IP address to public net, so that the users in public net could call some host
computer or serve that are in LAN.
Note: They only call some service, but not all LAN.
For example: 192.168.2.10 and 192.168.2.11 are IP address in LAN, 202.192.2.10 and
202.192.2.11 are the rightful IP address. When 192.168.2.10 communicates with
Internet, the router will transform the source IP address of packet to 202.192.2.10, and
transmit this packet. When router receive a packet which destination IP address is
202.192.2.10, router will transform the destination IP address to 192.168.2.10 and
transmit it to host computer in LAN.
Click “add” to add the list.
Protocol: You can choose TCP, UDP or ALL. When you choose ALL, you will not design
port number.
Inside Address: It is a private address typical, that is address of host computer in LAN.
Inside port: Users could design port when inner host computer communicate with
outside.
Outside Address: It is a rightful IP address.
Outside Port: Design a external port number.
Click “Apply” to make the configuration effective, “Back” is cancel.
- 16 -

1705Router Web Configuration Manual
1.5.3 Special Address Mapping
It is one of NAT. if you configure in NAT setting menu, it could make users in inner net
call public net; And configuration of port mapping could make users in public call some
host computer or service in inner net. But this special NAT port mapping is used to
make users in inner net call some host computer or service by public IP address of
router.
For example: 192.168.2.1 in LAN wants to call 192.168.2.2 in LAN by public IP
218.1.1.1, users should fill 218.1.1.1 in outside Address, fill 192.168.2.2 in inside
Address, and choose ALL protocol.
The configuration method of special address mapping is similar with port mapping.
Please refer to chapter 1.5.2.
1.5.4 Firewall
1705router is used to be a firewall by proper configuration.
The page layout shows the firewall function for every port. The firewall can screen two
directional data packet: IN(receive), OUT(send or transmit). You only need to edit the
corresponding filter list of port in order to make the firewall effective.
1. Edit the filter lists
Users could design the parameter of filter packet in filter list. If the router enable firewall
function, it will compare every entries of filter lists with source IP and destination IP of
data packet in order to judge receiving or transmitting the data packet.
Click the link of filter lists to enter configuration page layout.
- 17 -

1705Router Web Configuration Manual
The configuration method of filter lists is similar with access list configuration of NAT.
Their difference is: access lists of NAT is used to control communication of Internet and
PC in LAN, but filter lists of firewall is used to control the filter function of data packet.
Note:
The filter lists is a order sentence concourse, it match information of packet and parameter of access lists
by superincumbent order. Its judgement rule is that stop the matching rule if it pass some rule in access
lists, and it will not compare with latter rule.
There is a question in above configuration. The user’s purpose is that abandon all
packets except source IP 192.168.2.1. The figure is configured two items to achieve the
purpose. However the router match filter lists, its first row (deny row) has already finish
the matching, and it doesn’t match the second row. In this way, even if the source IP
address of data packet is 192.168.2.1, the router will filter this data packet.
The right method is that trade order of the two list item. You can adjust by up and dn
button in right.
2. Enable Firewall
Select “Enable” and click “Apply” to make the filter function effective.
1.5.5 Default Route
There are two parts in default route page layout:
 Route Cache Settings:
It is used to configure aging time of route cache. The default is 16. Usually it is
used to be default value.
 Default Route Table:
Click “Add Route” to add the default route.
