11.1.2 Enable internet users to access LAN resources
Scenario: You have set up an FTP server within your LAN.
Requirement: 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.
Solution: You can configure the virtual server function to reach the requirements.
Assume that the information of the FTP server includes:
−
IP address: 192.168.0.136
−
MAC address: D4:61:DA:1B:CD:89
−
Service port: 21
−
The WAN IP address of the router: 102.33.66.88.

Please ensure that router 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.

ISPs may block unreported web services to be accessed with the default port number 80. Therefore,
when the default LAN port number is 80, please change it to an uncommon port number (1024-65535)
manually, such as 9999.
−
The LAN port number can be different from the WAN port number.
