How can I have OpenVPN with a dynamic IP address?

Model: Archer C2300  
Hardware Version: V2
Firmware Version: 1.1.1 Build 20200918 rel.67850

Hello, I'm trying to ping my newly created DDNS but it looks like the ,,destination host it's unreachable" . I'm trying to use OpenVPN server in order to have a VPN connection when I'm leaving the country, but it looks like the certificate that I've created will become obsolete every time my ISP it's chainging the IP address, so idk what to do...Can somebody please help me? Thanks!

Upon successful DDNS creation you have to wait a little bit for the registration to take effect, associating the registered domain name with your current IP address.

If you're using TP-Link as a DDNS service provider here's the guide.

If you're using NO-IP as a DDNS service provider here's the guide.

@Robinson_Chera 

 

So you are describing two problems, is that right?

 

Which one of the DDNS services that the Acher C2300 supports are you using and if it's not TP-Link, what do your settings look like?

Have you tried to ping that domain from an external network (different ISP - not from your LAN) ?

Here's a video guide for configuring Open VPN on a TP-Link router.

How often does you public IP address change?

 

In case your Internet connection is established via PPPoE, L2TP or so, then make sure the connection is not set to On Demand or has a Max Idle Time set, because the public IP address usually changes every time the connection to the ISP is re-established.
