RBR20 not receiving VPN connection
Hello everyone, i'm trying to setup a vpn connection to access the network when I'm outside home. I followed the instructions provided in different posts: i configured and activated a dns (noip s...
- Sep 16, 2022I have tried to change to tcp, but without success. The openvpn client starts as before, and the connection to the orb is never made.
So I have set up port forwarding, dmz, bridge mode but it looks that the ports are always closed: at least, trying from services on internet to check the status, it appears that none of the changes I make are working.
I’m starting to suspect that my ISP is blocking all ports, since I am using not a “regular” service but a wireless one (through telephone networks) because there was no coverage in my area for other tecnologies..

How is the computer (Windows?) connected to the internet when the VPN connection is attempted?
- To the Orbi LAN?
- On another network (coffee shop? friend's house?)
- To a Hot Spot from a cell phone?

Cell phone Hot Spot is how I test my OpenVPN setup. Could you verify that the client.ovpn file looks like this:
client dev tap proto udp dev-node NETGEAR-VPN remote *******.mynetgear.com 12974 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key cipher AES-128-CBC comp-lzo verb 0 sndbuf 393216 rcvbuf 393216 route-method exe

Another wrinkle in OpenVPN lies with the client software used to make the connection. There are two types of VPN connection:
- tun (an abbreviation for tunnel) which typically uses port 12973, and
- tap (an abbreviation for network tap) which typically uses port 12974.
https://en.wikipedia.org/wiki/TUN/TAP#:~:text=TAP%2C%20namely%20network%20TAP%2C%20simulates,attaches%20itself%20to%20the%20device. Internet search will turn up numerous articles explaining the circumstances which would favor using one method over the other.
My RBR50 Orbi creates a client.ovpn file for Windows connections defining the connection as tap on port 12974. I have used this configuration with successfully with OpenVPN Connect. I have also manually changed the connection to use tun on port 12973.
(As an aside, please note that the Windows configuration is the only version that defaults to tap. Apple and Android do not support a tap connection so the "smart-phone" configuration is set for tun and the "non-windows" configuration is set for tun.)
Perhaps if there is a way to get a more detailed OpenVPN log something may reveal itself.
