Firewall and URL Filtering

The Firewall & URL Filtering page enables administrators to configure network security, manage traffic flow, and set rules for internet access. This page provides the flexibility to control incoming traffic, establish port-forwarding rules, and define URL filtering policies for optimal network security and accessibility.

How to Configure

  1. Login to Admin Panel
  2. Navigate to WAN/LAN > Firewall & URL Filtering



Incoming Firewall

The Incoming Firewall enhances device security by preventing unauthorized access and blocking unwanted or harmful connections. It can also render the device undiscoverable by dropping responses to ICMP requests (e.g., ping requests), reducing its exposure to potential threats.

  • Toggle the switch to activate or deactivate the incoming traffic firewall.



LAN Isolation

LAN Isolation enhances security by segregating traffic between the Local/MGMT and Guest networks, preventing unauthorized communication and ensuring data privacy. It is recommended to enable this feature for optimal network security.

  • Toggle the switch to enable/disable LAN isolation.




Port Forwarding

Port Forwarding is a network feature that redirects incoming traffic from specific ports on the router to designated devices or servers within the local (LAN) network. This allows external devices or applications to access services hosted internally, such as web servers, game servers, or CCTV systems. 

Modes:

  • Disabled: No port forwarding.
  • DMZ Host: Redirects all WAN traffic to a specific internal LAN IP.
  • Port Forwarding: Forwards specific port traffic based on defined rules.

     

Configuration Options:

  • DMZ Host:
    • Select Source IP (WAN).
    • Define Destination IP for DMZ host.
    • Click Save DMZ to apply.

       

  • Port Forwarding:
    • Protocol: Choose from TCP, UDP, ICMP, or GRE.
    • Source IP/Port: Optional source restrictions.
    • Destination IP/Port: Define internal LAN host and port.
    • Port Forwarding Rules:
      • Add, remove, and manage forwarding rules.



URL/Website Filtering

URL/Website Filtering is a network security feature that allows administrators to control access to specific websites or online content. By blocking or allowing specific URLs, domains, or categories of websites, this feature helps enforce usage policies, improve productivity, and protect users from malicious or inappropriate content. It is commonly used in schools, businesses, and parental controls to regulate internet access.

Modes:

  • Disabled: No URL filtering.
  • Blacklist: Block selected URLs.
  • Whitelist: Allow only specific URLs.

     

Domain Management:

  • Add domains to the list for filtering.
  • Manage the list by adding or removing entries.
