IP Screen | Scroll Prev Top Next More

The IP Screen is located under: Security » Security Settings » Screening. It is used to define specific remote IP addresses that will be allowed to connect, or not allowed to connect, to your local IP addresses. The remote IP addresses you place on the IP Screen can be associated with either all of you local IP addresses or with individual IPs. CIDR notation and the wildcards *, #, and ? are allowed.

For example:

*.*.*.* Matches to any IP address

#.#.#.# Matches to any IP address

192.*.*.* Matches to any IP that begins with 192

192.168.*.239 Matches to IP addresses from 192.168.0.239 to 192.168.255.239

192.168.0.1?? Matches to IP addresses from 192.168.0.100 to 192.168.0.199

•"deny from" and "allow from" are supported

•only IP values are imported (not domain names)

•CIDR notation is allowed but partial IP addresses are not.

•Each line can contain any number of space-separated or comma-separated IP addresses. For example, "deny from 1.1.1.1 2.2.2.2/16", ""3.3.3.3, 4.4.4.4, 5.5.5.5", and the like.

•Lines starting with # are ignored.

Remove

To remove an entry, select the entry in the list and click Remove.

Default Action

To specify the default action for connections from remote IP addresses that have not been defined, select an IP address from the list and click accept or refuse. Once a default action has been specified, you can change it by selecting the "<default>" node beneath the IP address and then selecting the new default setting.

When this option is chosen, connections from any IP addresses not specifically defined on the IP Screen will be accepted.

refuse

| The IP Screen will never block trusted IPs or local IPs.
