Cable Forum - View Single Post - Superhub OpenVPN config. Asus RT-AC87U (SH3 in modem mode)

Have we any OpenVPN experts out there?

I have set up my own OpenVPN server on the router.
Done the usual - set up openvpn config file using the routers export openvpn config file.
Set up my DDNS.
When connecting my Mac to the OpenVPN server on my home network everything works ok.
When trying to connect from a public network it will not connect.
The only thing I managed to connect from outside my home network was my iPhone over 4G using the OpenVPN app.
I presume it's a VPN subnet netmask conflict somewhere when trying to connect from outside my home network.
Tried lots of searches on google but although I am reasonably au-fait with some aspects of the router settings I was unable to find an answer to my issue.
Any help would be appreciated.
