The JBoss servlet container provides a built-in filter that can be used to configure IP Address Filtering. The org.apache.catalina.filters.RemoteAddrFilter can be configured in the web.xml file of any application to which you want to restrict access. The filter configuration allows you to specify initial parameters that allow or deny a set of IP addresses or a range of IP addresses represented by regex patterns.
For example:
<filter> <filter-name>Remote Address Filter</filter-name> <filter-class>org.apache.catalina.filters.RemoteAddrFilter</filter-class> <init-param> <param-name>deny</param-name> <param-value>127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1</param-value> </init-param> </filter> <filter-mapping> <filter-name>Remote Address Filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
For more information about RemoteAddrFilter, refer to the API documentation on the http://tomcat.apache.org Web site.
