An example of enabling internet users to access LAN resources using a domain name
Scenario: You have set up an FTP server within your LAN.
Goal: Open the FTP server to internet users and enable family members who are not at home to
access the resources of the FTP server from the internet with a domain name.
Solution: You can configure the DDNS plus port mapping functions to reach the goal.
Assume that the information of the FTP server includes:
−
IP address: 192.168.0.136
−
MAC address of the host: D4:61:DA:1B:CD:89
−
Service port: 21
−
Information of the registered DDNS service:
−
Service provider: oray.com
−
User name: JohnDoe
−
Password: JohnDoe123456
−
Domain name: o2849z7222.zicp.vip
Ensure that the Mesh device obtains an IP address from the public network. This function may not
work on a host with an IP address of a private network or an intranet IP address assigned by ISPs that
start with 100. Common IPv4 addresses are classified into class A, class B and class C. Private IP
addresses of class A range from 10.0.0.0 to 10.255.255.255. Private IP addresses of class B range from
172.16.0.0-172.31.255.255. Private IP addresses of class C range from 192.168.0.0-192.168.255.255.
