无法通过其httpendpointURL访问WSO2 ESB代理服务

Question

我们有一个WSO2 ESB代理服务，可以通过它的httpsendpoint访问。我想配置这个服务，使它也可以通过HTTP访问。我检查了carbon management控制台中的服务配置，并确认https和httpendpoint都已启用:https://10.20.0.20:8245/services/ http://10.20.0.20:8282/services/

此外，ESB_HOME}/repository/conf/axis2/中的axis2.xml文件似乎配置得很好。

编辑：下面是代理服务配置和netstat结果。

原来这只是防火墙的问题。端口8282在wso2防火墙（iptables）中被阻塞。谢谢你的回答！
