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 service) and activated the VPN, installed open vpn on my computer but the connection is never made. Specifically:

 

  1. my orbi system (RBR20, firmware V2.7.3.22, router mode) is connected to a modem which is provided by my ISP. I already set up this modem in bridge mode, disabling wifi.
  2. on the orbi logs, when attempting to connect through VPN, i do not see any voice related to VPN (failed connection or similar)
  3. the DNS is working, the status page on the orbi router is successful, and on the openvpn (verbose to 1) I can see that the ip is correctly resolved (the IP indicated is coherent with what I see on sites that provide the IP used

I have the log from OpenVPN:

could someone point me where is the error?

 

thanks

 

  • I 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
