You can allow and/or deny certain hosts to access Confluence via the following catalina classes:
org.apache.catalina.valves.RemoteAddrValve
org.apache.catalina.valves.RemoteCIDRValve
Solution
Solution 1: Remote Address Valve
The remote address valve supports the following attributes:
Attribute | Description |
|---|---|
className | Java class name of the implementation to use. This MUST be set to org.apache.catalina.valves.RemoteAddrValve. |
allow | A regular expression (using |
deny | A regular expression (using |

Add the following in Confluence server.xmlfile:

</Engine>Solution 2: Remote CIDR Valve
The remote CIDR valve allows you to use the IP address of the client. It supports the following configuration attributes:
Attribute | Description |
|---|---|
className | Java class name of the implementation to use. This MUST be set to org.apache.catalina.valves.RemoteCIDRValve. |
allow | A comma-separated list of IPv4 or IPv6 netmasks or addresses that the remote client's IP address is matched against. If this attribute is specified, the remote address MUST match for this request to be accepted. If this attribute is not specified, all requests will be accepted UNLESS the remote IP is matched by a netmask in the |
deny | A comma-separated list of IPv4 or IPv6 netmasks or addresses that the remote client's IP address is matched against. If this attribute is specified, the remote address MUST NOT match for this request to be accepted. If this attribute is not specified, request acceptance is governed solely by the |
