Access Control 

Access Control settings are used to block various services and protocols for specific client IP addresses. The 

configuration process is similar setting up port forwarding, except access control will deny specific functions to 

client IP addresses. There are pre-configured rules for specific functions that may be blocked or you can block 

specific UDP or TCP ports.  Access control operates for specific IP addresses across all WAN connections. If 

you are using more than one WAN connection, a single set of access rules is maintained for each controlled IP 

address that operates on all WAN connections. 

Note 

In order to use Port Access Control, Firewall support must be enabled. See 

Enable/Disable NAT and Firewall in the Advanced Security menu.

Remember, if the client IP address you want does not appear listed in the LAN IP pull-down menu, click on the 

New IP button to go to the LAN Clients menu.  

To block all traffic from the WAN port to a specific IP address, select the LAN IP address to block and click to 

check the Traffic Type __ Any selection box, then click the Apply button. This will block all traffic from the 

WAN port to the specified client. 

Remember to save the configuration changes.
