RBR750P - No IP address for VPN Connection

I have configured OpenVPN as per Netgear's instructions and it believes it connects from a laptop running Windows, but I cannot access anything on the LAN (e.g., RDP or router via browser).  Also, when I point to the icon for the connection in the system tray, while it says it is connected, the IP address for the connection is blank.

 

The following is the even log and config information from OpenVPN:

 

Event log for connection:

2024-06-18 09:47:41 WARNING: Compression for receiving enabled. Compression has been used in the past to break encryption. Sent packets are not compressed unless "allow-compression yes" is also set.

2024-06-18 09:47:41 DEPRECATED OPTION: --cipher set to 'AES-128-CBC' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305). OpenVPN ignores --cipher for cipher negotiations.

2024-06-18 09:47:41 WARNING: No server certificate verification method has been enabled.  See http://openvpn.net/howto.html#mitm for more info.

 

Config file:

remote  xxx.xxx.xxx.xxx 12974 (note: IP address is correct, but changed to xxx for privacy/security)

resolv-retry infinite

Any assistance in resolving this issue is appreciated.

 

Thanks!

  • Which version of OpenVPN is installed on the Windows laptop?

    Are you able to open the router web admin page using a device connected to the Orbi LAN and open the Attached Devices page?  When I do that, the device connected over VPN appears (usually at the bottom of the list) and shows as connection type "VPN"

      OpenVPN vv2.6.10

      I can view the connected devices, but there are no devices listed as connected to VPN.

      Thanks.  I just connected a Windows 11 PC to an RBR750 running OpenVPN server.  Here's how my Attached Devices screen appears on a computer connected to the RBR750 at IP 10.0.0.5 (sorry for the device name. I was confirming how many characters long a device name can be.)

       

       Notice the VPN device appears with local IP 10.0.0.6.  To confirm this, I opened a command window on the VPN computer and displayed ipconfig /all

      This confirms that the remote computer connected via a TAP adapter (the goofy default for Windows connections) and was assigned 10.0.0.6.  Opened a web browser to 10.0.0.1 (the RBR750 LAN IP) and it shows the same situation.
