The WSO2 Carbon products provides users with a browser based management console to administer the WSO2 products. All the WSO2 products comes with a management console to make the administration easier. When hosting the products ready for production, it's imperative to restrict the access to the mgt console from the external network.
Following steps shows how to restrict the access to WSO2 Carbon management console by IP.
Carbon itself gets added to the Tomcat runtime as a webapp. The "/carbon" is a servlet under it. Hence, we can use the Tomcat servlet filter, org.apache.catalina.filters.RemoteAddrFilter to restrict access.
1. Open CARBON_HOME/repository/conf/tomcat/carbon/WEB-INF/web.xml
2. Then, add the filter, org.apache.catalina.filters.RemoteAddrFilter, as follows. This filter can be used to restrict access by IP. Following is an example valve configuration to restrict the access only to localhost (considering both IPv4 and IPv6).
<filter> <filter-name>Remote Address Filter</filter-name> <filter-class>org.apache.catalina.filters.RemoteAddrFilter</filter-class> <init-param> <param-name>allow</param-name> <param-value>localhost|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>/carbon/*</url-pattern> </filter-mapping>
