Access Control⇑
Description
Specifies what sub networks and/or IP addresses can access the server. At the server level, this setting will affect all virtual hosts. You can also set up access control unique to each virtual host at the virtual host level. Virtual host level settings will NOT override server level settings.
Blocking/Allowing an IP is determined by the combination of the allowed list and the denied list. If you want to block only certain IPs or sub-networks, put * or ALL in the Allowed List and list the blocked IPs or sub-networks in the Denied List. If you want to allow only certain IPs or sub-networks, put * or ALL in the Denied List and list the allowed IPs or sub-networks in the Allowed List. The setting of the smallest scope that fits for an IP will be used to determine access.
Server Level: Trusted IPs or sub-networks must be specified in the Allowed List by adding a trailing "T". Trusted IPs or sub-networks are not affected by connection/throttling limits. Only server level access control can set up trusted IPs/sub-networks.
Tips
Use this at the server level for general restrictions that apply to all virtual hosts.
