RBR50 VPN Setup with OpenVPN Client on Mac

To verify, my router indeed has an external IP address, and I verified that my DDNS hostname does indeed resolve to the external IP of my RBR50. I also verified that when I use an app <on my smartphone> that specifies <my DDNS host name> when I am away from home (and just using my cell phone cellular signal), it access a server on my home network without any issues.  Obviously I am not using a VPN on my cellphone to get to my house - hence this effort to fix that.

I looked at the .ovpn file, and it shows the correct DDNS hostname, port 12973 (see below).  The only difference between my .opvn file and the recommendation from CrimpON (above - thanks for that) is that I don't have the "verb 5" entry as part of the entries at the top - which is expected.  I will add that and try it again.

• FYI, I did test this by (as was also suggested above) using my cellphone as a hotspot (and making sure my cellphone was not connected to anything via WiFi), then connecting my Mac to the cellphone hotspot.

client

dev tun

proto udp

remote <my DDNS host name> 12973

resolv-retry infinite

nobind

persist-key

persist-tun

<ca>

... plus a whole ton of additional stuff related to certificates and a Private key, and finally

cipher AES-128-CBC

comp-lzo

verb 5

Earlier when I said it 'worked' (my apologies), I should have said that the Mac OpenVPN client actually launched (after importing the .ovpn file meant for a smartphone), and I was able to view things on the Internet.  However, the OpenVPN client failed to connect.

Not being an expert on this stuff, I am not sure what entries in the log file are pertinent, but here are some that 'might' be important:  (Note: I can export that file and [after modifying some things to protect the guilty] attach it to another reply to this conversation thread if someone feels it is helpful)

• NOTE:  This configuration contains options that were not used
• Unsupported option (ignored)
• Connecting to [my hostname]:12973 (<my external IP address>) via UDP
• Server poll timeout, trying next remote entry...
• ... entries on reconnecting, including transmitting bypass route to /var/run/agent_ovpnconnect.sock
• Contacting <my external IP address> via UDP
• ... several repetitions similar to above
• ...eventually there is a message showing connection timeout after 5 attempts to reconnect.

It appears to me that (for whatever reason) the OpenVPN client either just cannot get to my RBR50, or the RBR50 won't allow the OpenVPN client on my Mac to connect.

To all that have replied, I truly appreciate the suggestions and ideas.  If anyone else has something to post, I will definitely pursue it.  Thanks!
