5 Router Connection Setup 
This chapter describes how to configure the basic settings for your router so that the computers on your LAN 
can communicate with each other and have access to the Internet. Network setup consists of LAN and WAN 
configurations. 
5.1 LAN Configuration 
5.1.1 LAN IP Address 
If you are using RX3141 with multiple PCs on your LAN, you must connect your LAN to the Ethernet ports on 
the built-in Ethernet switch. You must assign a unique IP address to each device residing on your LAN. The 
LAN IP address that identifies the RX3141 as a node on your network must be in the same subnet as the PCs 
on your LAN. The default LAN IP address for the RX3141 is 192.168.1.1. 
 
Definition 
A network node can be thought of as any interface where a 
device connects to the network, such as the RX3141’s LAN port 
and the network interface cards on your PCs. See Appendix 12 for 
an explanation of subnets. 
 
You can change the default IP address to reflect the true IP address that you want to use with your network. 
5.1.2 LAN Configuration Parameters 
Table 5.1 describes the configuration parameters available for LAN IP configuration. 
Table 5.1. LAN Configuration Parameters 
Setting Description 
Host Name For identification only. 
IP Address 
The LAN IP address of the RX3141. This IP address is used by your 
computers to identify the RX3141’s LAN port. Note that the public IP address 
assigned to you by your ISP 
is not your LAN IP address. The public IP 
address identifies the WAN port on the RX3141 to the Internet. 
Subnet Mask 
The LAN subnet mask identifies which parts of the LAN IP Address refer to 
your network as a whole and which parts refer specifically to nodes on the 
network. Your device is preconfigured with a default subnet mask of 
255.255.255.0.

5.1.3  Configuring the LAN IP Address 
Follow these steps to change the default LAN IP address. 
1.  Log into Configuration Manager, and then double click 
Router Setup Î Connection menu. The 
Router Connection Setup configuration page is then displayed as shown in Figure 5.1. 
 
Figure 5.1. Router Connection Setup Configuration – LAN Configuration 
2.  (Optional) Enter the host name for RX3141. Note that the host name is used for identification only 
and is not used for any other purpose. 
3.  Enter the LAN IP address and subnet mask for the RX3141 in the spaces provided. 
4.  Proceed to the WAN Configuration section for instructions on setting up the WAN port if you have 
not yet done so. 
5. Click 
 to save the settings. If you are using an Ethernet connection for the current 
session, and change the IP address, the connection will be terminated. 
6.  You will see the following message displayed as shown below. 
 
7.  You will then be prompted to log back into the Configuration Manager once the timer elapses.

5.2 WAN Configuration 
This section describes how to configure WAN settings for the WAN interface on the RX3141 that 
communicates with your ISP. You’ll learn to configure IP address, DHCP and DNS server for your WAN in this 
section. 
5.2.1 WAN Connection Mode 
Four modes of WAN connection are supported by the RX3141 – PPPoE (multi-session), PPPoE unnumbered, 
dynamic IP and static IP. You may select one of the WAN connection modes required by your ISP from the 
Connection Mode drop-down list in Network Setup Configuration page as shown in Figure 5.2.

5.2.2 PPPoE 
PPPoE connection is most often used by ADSL service providers.

5.2.2.1  WAN PPPoE Configuration Parameters 
Table 5.2 describes the configuration parameters available for PPPoE connection mode. 
Table 5.2. WAN PPPoE Configuration Parameters 
Setting Description 
Connection Mode Select PPPoE from the connection mode drop-down list. 
PPPoE Session Select the PPPoE session ID for this PPPoE session. Note that only two 
simultaneous PPPoE sessions are supported. 
Enable Check or uncheck this box to activate this PPPoE session. 
Connection on Demand Check “Enable” or “Disable” radio button to enable/disable this option.  
Disconnect after Idle (min) Enter the inactivity timeout period at which you want to disconnect the Internet 
connection when there is no traffic. A value of 0 means no activity time out. 
Note that SNTP service may interfere with this function if there are activities 
from the service. 
User Name and Password Enter the username and password you use to log into your ISP. (Note: this is 
different from the information you used to log into Configuration Manager.) 
Service Name Enter the service name provided by your ISP. Service name is optional but 
may be required by some ISP. 
IP Address Enter a static IP address here only when your service provider requires a 
static IP for PPPoE connection. This IP address must be provided by your 
service provider. Most service providers do not require user to use a static IP 
for PPPoE connection. 
Primary/Secondary DNS 
Server IP address of the primary and/or secondary DNS are optional as PPPoE will 
automatically detect the DNS IP addresses configured at your ISP. However, 
if there are other DNS servers you would rather use, enter the IP addresses 
in the spaces provided. 
Status On: PPPoE connection is active. 
Off: PPPoE connection is inactive. 
Connecting: RX3141 is trying to connect to your ISP using PPPoE connection 
mode. 
Manual 
Disconnect/Connect Click the Disconnect or Connect button to disconnect or connect to your 
service provider using the PPPoE connection mode.

Connection menu. 
2.  Configure PPPoE settings as you normally would for each PPPoE session as described in 
section 5.2.2.2 “Configuring PPPoE for WAN”. Note that maximum of two PPPoE sessions are 
supported. The following figures show the settings for the two PPPoE sessions.

3.  Configure firewall outbound ACL rules to forward the designated traffic to each intended PPPoE 
session. Please refer to section 9.5 “Configuring Outbound ACL Rules” for instructions on setting 
up ACL rules. Figure 5.7 and Figure 5.8 show the settings for the two outbound ACL rules – one 
specify the destination network using the network address and subnet mask and the other using 
the domain name. Only one of the two ACL rules is needed. However, if you intend to use IP 
address and the domain name to access the myService network, you’ll need to configure both 
rules.

Packets to PPPOE1 Session Figure 5.8. WAN – Second ACL Rule Settings 
(using domain name) for Forwarding Packets to 
PPPOE1 Session 
4.  Verify that you have all the rules properly configured as indicated in the “Existing Outbound ACL” 
table as shown in Figure 5.9. Note that the third rule is the default outbound ACL rule that allows 
all the outbound traffic to go through the firewall. You’ll have to configure this rule (see the default 
outbound ACL settings in Figure 5.10) if you had deleted. The third rule is used to forward all the 
outbound traffic to PPPoE0 session except those intended for PPPoE1 session.
