有端口限制么 开了7000端口 但是怎么也访问不了

tomcat server.xml的配置

<?xml version='1.0' encoding='utf-8'?>

<Connector port="7000" protocol="HTTP/1.1"
           connectionTimeout="20000" URIEncoding="UTF-8"
           redirectPort="7043" />
<Engine name="Catalina" defaultHost="localhost">
  <Host name="localhost"  appBase="webapps"
        unpackWARs="true" autoDeploy="true">
    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
           prefix="localhost_access_log." suffix=".txt"
           pattern="%h %l %u %t &quot;%r&quot; %s %b" />
  </Host>
</Engine>
