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 refered 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
Customer IP filter are different from Port forwards, or Block All traffic because they allow greater
scopes of IP addresses to be included in the block.
To access IP Filters, click on Advanced>Firewall>IP Filters.
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 above on LAN
Clients under the Advanced Menu.
