The OpenVPN server is setup on the TP-Link C3150 V2 router. The DDNS is setup on the router with TP-Link as the provider. VPN settings are all correct. VPN server is active and can confirm that a VPN connection is enabled. With regards to network topology, the internet connection comes in via coax into a cable modem and that goes out to the TP-Link C3150 V2 router. I have about 10 clients connected via wired and wireless. After enabling remote connections to the VPN server via Apple iPhone and Mac clients, there is no access to the server LAN. I've attached a screenshot of the server setup which was the default setup with the exception of the client access option, which I changed to Internet and Home Network. I reset my router twice and went through the same steps with no success when it came to being able to access the server side LAN.

Hello, thanks for reporting this issue.

 

Please check the Firewall and Anti-Virus software on the server: generally, Windows Firewall would block the packages from the VPN Client, disabling the firewall on Windows PC for "public" and "private" network will be helpful. Windows Firewall is located at "Control panel->System and Security->Windows Firewall/Windows Defender Firewall".


If this doesn't help, please help verify some details, and we will try to figure it out:
1. Kindly check the below VPN setup instructions again to confirm all the settings on the C3150 are correct:

BTW, please also provide us your network topology.
2. If the above guide doesn't help, please tell us what is the WAN IP address of the C3150 and it is suggested to configure the DDNS:

3. Please check the VPN Tunnel: login the web interface, and on the VPN Server-> VPN Connections, we can see the status of the VPN Server, confirm if there is a VPN connection enabled. If not, which means the VPN setup is not successful.
