Wireless Cable Gateway CG3000D-1CXNAS MAC Filtering By default, the gateway allows any connected PC to access the Internet through. The MAC Filtering screen lets you block specific computers, based on their MAC address, from access to the Internet on selected days and times. To use MAC filtering to block Internet access for a specific computer: 1. In the main menu, under Advanced, select MAC Filtering. The Trusted Devices table shows computers that have access to the Internet through the gateway.
Wireless Cable Gateway CG3000D-1CXNAS IP Filtering By default, any computer will be allowed access to the internet through your gateway.

Wireless Cable Gateway CG3000D-1CXNAS Port Blocking You can use port blocking to block outbound traffic on specific ports. Outbound traffic rules control access to outside resources from local users.The default rule is to allow all access from the LAN side to the outside. You can use port blocking to add predefined or custom rules to specify exceptions to the default rule. Note: Any outbound traffic that is not blocked by rules that you have created is allowed by the default rule.
Wireless Cable Gateway CG3000D-1CXNAS Port Forwarding A firewall has default rules for inbound traffic (WAN to LAN) and for outbound traffic. Port forwarding affects the inbound rules. These rules restrict access from outsiders. By default, the gateway blocks access from outside except responses to requests from the LAN side. You can use port forwarding to add rules to specify exceptions to the default rule.
Wireless Cable Gateway CG3000D-1CXNAS Considerations for Port Forwarding • If the IP address of the local server PC is assigned by DHCP, it might change when the PC is rebooted. To avoid this, you can assign a static IP address to your server outside the range that is assigned by DHCP, but in the same subnet as your LAN. By default, the IP addresses fromf 192.168.0.2 through 192.168.0.9 are reserved for this purpose. • Local PCs must access the local server using the PCs’ local LAN address (192.168.0.
Wireless Cable Gateway CG3000D-1CXNAS 2. For each port trigger, enter the settings in the Port Trigger List: • Trigger Range. To specify the range of outgoing ports that will be monitored to trigger the incoming port forwarding rule, enter the Start Port and End Port. • Target Range. To specify the range of incoming ports that will be opened when triggered, enter the Start Port and End Port. • Protocol. Select the protocol for the ports: 3. Select the Enable checkbox for the port trigger. 4.
Wireless Cable Gateway CG3000D-1CXNAS LAN IP Setup The LAN IP screen allows you to configure LAN services such as the IP address of the gateway and DHCP. The TCP/IP and DHCP default values work fine in most cases. Note: If you disable the DHCP server, you will need to assign to your computer a static IP address to reconnect to the gateway and enable the DHCP server again. To configure LAN IP settings: 1. In the main menu, under Advanced, select LAN IP. 2.
Wireless Cable Gateway CG3000D-1CXNAS Reserving an IP Address for DHCP Use To reserve an IP address for DHCP use, enter the DHCP server reservation settings for the private LAN under DHCP Reservation Lease Info in the LAN Setup screen.
