Goal: Open the FTP server to internet users and enable yourself to access the resources of the FTP
server from the internet using a domain name when you are not at home.
Solution: You can configure the DDNS plus port forwarding functions to reach the goal.
Assume that the information of the FTP server includes:
− IP address: 192.168.1.136
− Service port: 21
The information of the registered DDNS service:
− Service provider: DynDNS.org
− User name: JohnDoe
− Password: JohnDoe123
− Domain name: o2849z7222.zicp.vip
Please ensure that the ONT obtains a public IP address. 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 to 172.31.255.255.
Private IP addresses of class C range from 192.168.0.0 to 192.168.255.255.
Configuring procedure:
Step 1 Log in to the web UI of the ONT.
Step 2 Add a Dynamic DNS rule.
1. Choose Services > Service > Dynamic DNS.
2. Select Enable.
3. Choose a service provider in DDNS Provider, which is DynDNS.org in this example.
4. Enter the Hostname, which is o2849z7222.zicp.vip in this example.
5. Select the WAN interface that the port forwarding rule applies to.
