Advanced>IP Filters
The IP filters page allows you to specify Normal Port Forwards, Block ALL traffic
to specific LAN Clients or specify Custom IP filters that will control the flow of data
across the router.
Custom IP Filters (often also referred to as ‘Access Control Lists’ ) allow you to
specify individual rules that will deny traffic by defining the following:
• Source IP address or IP Subnet
• Destination IP address or Subnet
• Port or Port range
• Protocol
Custom IP filters are different from Port forwards, or Block All traffic because they
allow greater scopes of IP addresses to be included in the block.
Note: You must have at least one LAN Client in your LAN clients table before IP
filters can be created. To create a LAN Client, see the section below on LAN
Clients under the Advanced Menu.
