1、编辑/etc/vmware/firewall/service.xml 

1. vi /etc/vmware/firewall/service.xml

2、在该文件重中倒数第二行开始添加以下内容：

1. <!-- Firewall configuration information for VNC -->
2. <service id='0040'>
3. <id>VNC</id>
4. <rule id='0000'>
5. <direction>inbound</direction>
6. <protocol>tcp</protocol>
7. <porttype>dst</porttype>
8. <port>
9. <begin>40000</begin>
10. <end>60000</end>
11. </port>
12. </rule>
13. <enabled>true</enabled>
14. <required>false</required>
15. </service>

3、执行以下命令以使配置文件生效：

1. esxcli network firewall refresh

4、查看是否已经生效：

1. esxcli network firewall ruleset list | grep VNC
2. VNC true
