Firewall or IP filtering can be performed using either an CM685P/T or CM820P/T to setup a secure LAN communications. MAC and IP address filtering feature can be activated by setting up Firewall > MAC/IP/Port Filtering. Please see below:
Port Forwarding feature is the function of translating and forwarding an inbound connection to a destination with a defined port number within the local area network.
Port Forwarding: Enable or disable the feature
IP Address: Local IP address to be assigned and a local port
Port Range: External Port
Protocol: TCP/UDP, TCP Only, UDP Only
Interface: Recommend to select "WAN" for inbound connection
Comment: Notes/comment to define the rule
To configure Port Forwarding, navigate to: Firewall > Port Forwarding:
DDNS feature allows a dynamic public IP to be used with the modem, and a fixed domain name is allocated (acquired thru DNS service provider) to enable remote access from anywhere.
DynDNS requires a SIM card enabled with a public IP, either dynamic or static. Please contact your network service provider to setup this feature.
To set DDNS service, go to Administration > Management:
Account : Username in your DDNS provider/account name
Password : DDNS password
DDNS : domain name assigned to your modem
Prior to acquiring the DDNS name to be assigned to your modem, you need to sign up for the DDNS service. In the example below, we use www.dyn.com :
- Login to the web service www.dyn.com and sign up for the service to create your user account.
- Add/create the DDNS name that will be assigned to your modem.
- Enter the DDNS name and IP details of your modem. The IP address will be the public IP address assigned by the network service provider (i.e. Telstra). You can view this parameter on the status page of your modem user interface.
- Initial condition
Connect the router to a PC via the LAN port. Open the UI using the router gateway IP address (Default: 192.168.8.1). Check the Ethernet port status as per below:

A public IP address is any valid address, or number, that can be accessed over the Internet. A public IP address is glogally unique and can only be assigned to a unique device.
A private IP address is any number or address assigned to a device on a private TCP/IP Local Area Network that is accessible only within the Local Area Network. There are three private IP blocks (1 class A, 1 class B and 1 class C) as outlined in the table below:
|Class||Starting IP Address||Ending IP Address||# of Hosts|
For a resource inside the Local Area Network to be accessible over the Internet, a device within the Local Area Network must be connected to the Internet with a public IP address, and the networking must be appropriately configured.
A public IP address is particularly required if the device needs to be accessed remotely via the internet.
Below outlines the suggested configuration of your SIM card for a public IP address in Australia:
Call or visit your Telstra Business Representative to configure your SIM card for a dynamic public IP by entering the product code GPTEXB3. Once this is entered, the APN that needs to be assigned in the APN field of the router is “telstra.extranet”. Both username and password are usually left blank. Please note, to have a public IP enabled, you need to have a post-paid account with Telstra.
Call or visit your Optus Business Representative to configure your SIM card for a public IP. The APN that needs to be assigned in the APN field of the router is “yesbusinessip”. This will provide a static public IP based on network availability. Both username and password are usually 'optus' when using the APN 'yesbusinessip'. However, please check with your Optus authorized representative.
Vodafone provides a private IP only. The APN is live.vodafone.com.
APN's (Access Point Names) are used by GPRS/3G/4G cellular data networks in establishing packet data connections. The APN determines how the carrier network passes IP traffic to the destination network (i.e. what IP addresses are assigned to the console server, what security methods are used etc).
Upon purchase of a SIM card, you will be provided information by your wireless carrier for configuring the data connection e.g.
- APN (Access Point Name)
- Pin Code (optional PIN code which may be required to unlock the SIM card)
- Data Number (the sequence to dial to establish the connection, defaults to *99***1#)
- Username/ Password (optional)
- Dial string (optional AT commands)
Common APNs for Australian network providers are:
Additionally, please check and confirm from your network (SIM) provider the APN details assigned to your SIM card. APNs, IP-functions, and other functionalities may vary from time to time and is entirely network-dependent.
APN's (Access Point Names) are the most fundamental requirement in 3G/4G data communications. A wrong APN setting will result in disconnected system or inactive connection. Please ensure that you confirm this information with your network provider.
IMPORTANT: The main router should have an active Internet connection before cascading the secondary router; otherwise you need to set it up first.
Step 1: Check and take note of the IP address of the main router.
Step 2: Connect a computer to the secondary router (desktop or laptop to one of the Ethernet ports of the second router). In this image, Comset router is acting as the 2nd router.
Step 3: Access the web-based setup page of the secondary router. By default, IP address is “192.168.8.1”.
Step 4: Setup the secondary router to “Gateway Mode”.
Step 5: Connect the cable to “LAN” Port of the Main Router to the “WAN” Port of the secondary router using an Ethernet RJ45 cable.
Yes. It’s a generic adapter that you can purchase from any electronic store. For direct current source, use input powers supply +5～+40V (if your CM685P/T supports 50V, the option is +5~+50V). In most cases, the standard configuration is 12V/1A.
The router can be setup in three different configurations: Bridge, Gateway, and Access Point Client. In this setup, we are going to configure the CM685 as Access Point Client Mode that allows the router to act the wireless client.
Note: In this setup, you need two CM685 routers:
Step 1: Connect PC directly to the main router using a RJ-45 cable. Access the web-based setup page of the main router. For instructions, click here.
Step 2: Navigate to “Operation Mode”. Configure the main router as “Gateway” mode, and click “Apply”.
Step 3: Click on “WiFi” and select the “Basic” option to customize your wireless settings.
Under “WiFi”, click on “Security” option and setup Security Password on the router.
Step 4: Take note of the “Frequency Channel” and “Extension Channel” as we will use same value on the secondary router. Then Click on “Apply” to save changes.
Step 5: Navigate to “Internet Settings” and Click on “WAN”. Make sure that the WAN Connection Type is set to “Cellular Network”.
Step 6: Test your Wi-Fi connection by connecting a laptop to the wireless network. If it works then main router is properly configured. Proceed to step 7.
Steps on how to setup the Secondary Router
Step 7: Connect PC directly to the main router using a RJ-45 cable. Access the web-based setup page of the main router. For instructions, click here.
Step 8: Navigate to “Operation Mode”. Configure the router as “Access Point Client” mode, and click “Apply”.
Step 10: Navigate to “WiFi”. Once you have selected AP Client Mode, another option will appear as “AP Client”. Configure the Wireless settings of the secondary router with same SSID.
The “Frequency (Channel)” and “Extension Channel” should be the same as the Main Router.
Step 11: Navigate to Internet Settings > WAN, set the connection type as “DHCP (Auto config)” and then click “Apply”.
Step 12: Click on Status, if it shows “Operation Mode” as AP Client Mode , that means the secondary router now acts as Access Point Client.
Failover is switching to a standby network upon the failure or termination of the main network. Once Failover backup configuration is enabled on the router, it usually operates automatically without any human intervention.
Confirm that the main (upper) router’s side connects to the internet and DHCP Server is enabled and working. For route fail over feature, please first make the main network and backup network both work before you activate the feature.
With this configuration, the router will work at cellular mainly, and if cellular is failed, it switches to DHCP automatically after some time. And it will automatically switch to cellular when cellular is fixed.
Step 1: Connect PC/Laptop directly to the LAN port of the router using RJ-45 cable.
Step 2: Access the web-based setup page of the Comset router. For instructions, click here.
Step 3: Navigate to Operation Mode and make sure it’s set to “Gateway”.
Step 4: Click on Link Backup to setup.
Step 5: Navigate to Internet Settings > WAN. Make sure that Cell Network is selected.
Step 6: Unplug the RJ-45 cable that is connected to the LAN Port of the CM685 Router.
Step 7: Use the existing RJ-45 cable and connect it from the LAN port of the ADSL router going to the WAN Port of the CM685 Router.
