TVP-221H User’s Guide 

from the Internet. 

To manage this device via the Internet, you need to know the IP 
Address of this device, as seen from the Internet. This IP Address is 
allocated by your ISP. However, if you are using a Dynamic IP 
Address, this value can change each time you connect to your ISP. 
There are 2 solutions to this problem: 
Have your ISP allocate you a Fixed IP address.  
Use the DDNS feature (Internet menu) so you can connect using a 

Domain Name, rather than an IP address. 

 

1.  Ensure your Internet connection is established, and start your Web Browser. 
2.  In the "Address" bar, enter "HTTPS://" followed by the Internet IP Address of the TVP-

221H. If the port number is not 80, the port number is also required. (After the IP Address, 
enter ":" followed by the port number.)  
e.g.  

HTTPS://123.123.123.123:8080 

This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080.

Click the "Browse" button and browse to the location on your TFTP
