Overview
The NetComm 3G25W-R integrates a Wireless LAN and 3G WAN into
one unit. Connection to the Internet is achieved through either a 3G
service or via a fixed line xDSL/Cable/Satellite connection to the
3G25W-R's WAN port, providing you with the flexibility to choose how
you access the Internet. The 3G25W-R's automatic failover ensures
you are always connected by activating the 3G connection should the
xDSL/Cable/Satellite connection drop out.
Users are able to share a single 3G connection via both a wired and
wireless connection to the 3G25W-R. With a built in 802.11n wireless
access point, this router provides wireless speeds of up to 150Mbps,
150% faster than 11g technology¹. On top of this, the 3G25W-R has
four LAN ports for wired connections to multiple devices. Rather than
being restricted to certain USB modems, the 3G25W-R allows the
user to simply insert an active SIM and utilise 3G Mobile Broadband
for internet connectivity.
The 3G25W-R includes advanced security features such as VPN
pass-through, a full complement of wireless security options and a
built in firewall.
1 Maximum wireless signal rate and coverage values are derived from IEEE Standard 802.11g and
802.11n Draft 2.0 specifications. Actual wireless speed and coverage are dependent on network and
environmental conditions included but not limited to volume of network traffic, building materials and
construction/layout.

    Forwarding Rules  The Forwarding Rules page allows you to configure the port forwarding management on the router. Click on any of the menu items on the left to access the respective settings page. Forwarding rules are a necessary feature as by default NAT (Network Address Translation) will automatically block incoming traffic from the Internet to the LAN unless a specific port mapping exists in the NAT translation table.
  • Page 34 Forwarding Rules > Virtual Server  A virtual server is defined as a Service Port, and all requests to this port will be redirected to the computer specified by the Server IP. Virtual Servers can also work with Scheduling Rules, and give you more flexibility on Access control.
  • Page 35 Some applications like On-line games, Video conferencing and Internet telephony require multiple connections to the internet. Because of that, these applications cannot work with a pure NAT router such as the 3G25W-R. The Special Applications feature allows some of these applications to work with this router. If this fails to make the application work, try to set up that computer as the DMZ host instead.
  • Page 36 Forwarding Rules > Miscellaneous  DMZ (Demilitarized Zone) Host is a computer without the protection of firewall. It allows that particular computer to be exposed to unrestricted 2-way communication to the internet. It is mostly used for Internet games, Video conferencing, Internet telephony and other special applications. To enable DMZ, enter the IP address of the PC and tick on Enable.

There are two types of packet filter, Outbound Packet Filter which applies to all outbound packets and Inbound Packet Filter which only applies to packets that are destined for a Virtual Server or DMZ host only. To enable an Outbound Filter, please make sure to tick the Enable tick box on the top of the page.
  • Page 39 To access the Inbound Packet Filter page, click on the “Inbound Filter” button on the bottom of the Outbound Filter page. All the settings on this page are similar to the one for the Outbound Filter. Click “Save” to save the settings or “Undo” to cancel.

To enable the Domain Filter please make sure to tick the Enable tick box on the top of the page. Log DNS Query. Please tick the Enable tick box if you want to log when someone accesses specific URLs.
  • Page 41 Security Setting > URL Blocking  URL Blocking will block LAN computers from connecting to a pre-defined website. The major difference between Domain Filter and URL Blocking is that Domain Filter require users to input a suffix (e.g. xxx.com, yyy.net) while URL Blocking only requires you to input a keyword. To enable URL Blocking please make sure to tick on Enable tick box on the top of the page.

Check Enable to enable this function. Setting of Email alert Check if you want to enable Email alert (send syslog via email).
  • Page 46 Advanced Setting > Dynamic DNS  The Dynamic DNS feature enables users to have a static domain name for their internet connection even when their internet connection IP address is dynamic. By mapping the host name to the current public IP address of the router, users who want to connect to the router or any services behind the router from the internet can just use the Dynamic DNS hostname instead of the IP Address which might change every time the router connects to the Internet.

Remote IP: Ports Define the Remote IP address and port to apply QoS to. QoS Priority: This defines the priority level of the current Policy Configuration. Packets associated with this policy will be serviced based upon the priority level set.
  • Page 48 Routing tables allow you to determine which physical interface address to use for outgoing IP data. If you have more than one router and subnet, you will need to configure the routing table to allow packets to find the proper routing path and allow different subnets to communicate with each other. These settings are used to setup the static and dynamic routing features of the 3G25W-R.
  • Page 49 Dynamic Routing: Routing Information Protocol (RIP) will exchange information about different host destinations for working out routes throughout the network. Please only select RIPv2 if you have a different subnet in your network. Otherwise, please select RIPv1. Static Routing: For static routing, you can specify up to 8 routing rules. You need to enter the destination IP address, subnet mask, gateway, hop for each routing rule, and then enable the rule by clicking the Enable checkbox.
