Retype the password that was entered in the L2PT field. Ensure that these two passwords are identical or an error will occur. A value of 0 means that the PPP connection will remain connected. If your network account is billed according to the amount of time the Router is actually connected to the Internet, enter an appropriate Idle Time value (in minutes). This will disconnect the Router after the WAN connection has been idle for the amount of time specified. The Maximum Transmission Unit size may be changed if you want to optimize efficiency for uploading data through the WAN interface. The default setting (1400 bytes) should be suitable for most users. Some user may want to adjust the setting to optimize performance for wireless traffic or when low latency is desired (such as with Internet gaming). It is highly recommended that the user research how adjusting the MTU may affect network traffic for better or worse. Select the desired option: Always on, Manual, or Connect on demand. Most users will want to choose the default connection setting, Always on.

HOME - LAN

You can configure the LAN IP address to suit your preference. Many users will find it convenient to use the default settings together with DHCP service to manage the IP settings for their private network. The IP address of the Router is the base address used for DHCP. In order to use the Router for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of the Router. The IP addresses available in the DHCP IP address pool will change automatically if you change the IP address of the Router. See the next section for information on DHCP setup.
LAN Settings window To change the LAN IP Address or Subnet Mask, type in the desired values and click the Apply button. Your web browser should automatically be redirected to the new IP address. You will asked to login again to the Routers web manager.

HOME - DHCP

The DHCP server is enabled by default for the Routers Ethernet LAN interface. DHCP service will supply IP settings to workstations configured to automatically obtain IP settings that are connected to the Router though the Ethernet port. When the Router is used for DHCP it becomes the default gateway for DHCP client connected to it. Keep in mind that if you change the IP address of the Router the range of IP addresses in the pool used for DHCP on the LAN will also be changed. The IP address pool can be up to 253 IP addresses.
DHCP window To display this window, click the DHCP button in left menu. Any active DHCP Clients appear at the top of the window in the DHCP Clients List. The IP address and MAC address for active DHCP clients are displayed in the list. The two options for DHCP service are as follows: You may use the Router as a DHCP server for your LAN. You can disable DHCP service and manually configure IP settings for workstations. Follow the instructions below according to which of the above DHCP options you want to use. When you have configured the DHCP Settings as you want them, click the Apply button to commit the new settings. 42
Conceptronic C54BRS4A Use the Router for DHCP
To use the built-in DHCP server, click to select the DHCP Server option if it is not already selected. The IP Address Pool settings can be adjusted. The Starting IP Address is the lowest available IP address. If you change the IP address of the Router this will change automatically to be 1 more that the IP address of the Router. The Ending IP Address is the highest IP address number in the pool. Select the desired Lease Time from the drop-down menu. This is the amount of time that a workstation is allowed to reserve an IP address in the pool if the workstation is disconnected from the network or powered off.

Disable the DHCP Server To disable DHCP, click the Disabled DHCP Server radio button and then click the Apply button. Choosing this option requires that workstations on the local network must be configured manually or use another DHCP server to obtain IP settings. If you configure IP settings manually, make sure to use IP addresses in the subnet of the Router. You will need to use the Routers IP address as the Default Gateway for the workstation in order to provide Internet access.

Menu - Advanced

The Advanced folder contains main windows for Virtual Server, Special Applications, Firewall Rules, DMZ, IP Filters, MAC Filters, URL Blocking, Domain Blocking, Wireless Performance, and Dynamic DNS.

ADVANCED VIRTUAL SERVER

Use this window to set up forwarding rules applied to inbound (WAN-to-LAN) traffic. The Virtual Server function allows remote users to access services on your LAN such as FTP for file transfers or SMTP and POP3 for e-mail. The Wireless Broadband Router will accept remote requests for these services at your Global IP Address, using the specified TCP or UDP protocol and port number, and then redirect these requests to the server on your LAN with the LAN IP address you specify. Remember that the specified Private IP Address must be within the useable range of the subnet occupied by the Router. UDP/TCP port redirection is used to direct inbound traffic to the specified servers or workstations on your private network. Port redirection can also be used to direct potentially hazardous packets to a proxy server outside your firewall. For example, you can configure the Router to direct HTTP packets to a designated HTTP server in the DMZ. You can define a set of instructions for a specific incoming port or for a range of incoming ports. Each set of instructions or rule is indexed and can be modified or deleted later as needed. Below you will find a list of some common used ports and their corresponding application: Port 25 Application FTP Data (FTP Server) FTP (FTP Server) SSH (Secure Shell) Telnet SMTP (Mail Server Outgoing) Port 5900 Application HTTP (Web Server) POP3 (Mail Server Incoming) Remotely Anywhere VNC VNC
For more ports and their corresponding applications, see: http://portforward.com/cports.htm Note: When you are using an application which supports UPnP Port Mapping, the router can be automatically configured by the application when needed. In that case, you dont need to setup your port mappings manually. Note: When using Virtual Server rules, it is advised to configure the computer(s) with a Fixed IP Address instead of a Dynamic IP Address. 44

Conceptronic C54BRS4A Note: In the picture below you will see an example of a Virtual Server configuration.
Virtual Server window 1. 2. 3. 4. Set the Virtual Server rule to Enabled. Enter a name for your Virtual Server Rule in the Name field. Enter the IP Address of your computer/server which needs the Virtual Server rule. Select the Protocol for your Virtual Server rule: TCP, UDP or Both.
Note: If you do not know which protocol you need for your Virtual Server Rule, select Both. This option will pass both TCP and UDP traffic to the configured IP Address of your computer/server. 5. 6. 7. Enter the desired Port of your computer/server which needs the Virtual Server rule. Enter the port which must be visible on the outside of your internet connection. Click Apply to apply the created Virtual Server rule.

ADVANCED - DDNS

The Router supports DDNS (Dynamic Domain Name Service). The Dynamic DNS service allows a dynamic public IP address to be associated with a static host name in any of the many domains, allowing access to a specified host from various locations on the Internet. This is enabled to allow remote access to a host by clicking a hyperlinked URL in the form hostname.dyndns.org, Many ISPs assign public IP addresses using DHCP, and this can make it difficult to locate a specific host on the LAN using standard DNS. If for example you are running a public web server or VPN server on your LAN, this ensures that the host can be located from the Internet if the public IP address changes. DDNS requires that an account be set up with one of the supported DDNS providers.
Dynamic DNS window Please note that DDNS requires that an account be setup with one of the supported DDNS servers prior to engaging it on the Router. This function will not work without an accepted account with a DDNS server. Enter the required DDNS information and click Apply to set this information in the Router.
