Thank you! And wow! I am very impressed how easy it was to upgrade to Amahi 9! I'm running it now.I would try this route first before doing a new intall.Or should I be safe if I do the following?
1. Change my router's gateway to 192.168.0.x to match my HDA profile.
2. Change my gateway settings in HDA and confirm I can access my shares and DHCP/DNS from Amahi is working for my home network clients.
3. Remove all apps from my Amahi 8 installation and reboot the server.
Then follow the http://docs.amahi.org guidance for Upgrading Amahi 8 to Amahi 9. It works fairly well and would save you time.
The HDA OS Migration Guide is more for those who cannot do an upgrade.
I managed to install OpenVPN again and then install HDAConnect on one of my Windows 10 laptops and connected it to my phone's hotspot and bam, it connected successfully!! That's with all the default settings and keeping UDP port forwarding rather than TCP I described in my first post.
Thank you very much!
Now, the only issue I have is how can I browse to my dashboard or share while connected via VPN to my server?
I assume that I have to use my full domain name. Is my domain the the one listed in the Control Panel on Amahi.org as "Home Domain"? So, if the control panel says "mydomain.net", to access my dashboard I should use http://hda.mydomain.net?
I tried that and it does not work.
I also tried to use "\\hda" as well as "\\hda.mydomain.net" to access my shares in Windows Explorer without success.
What am I missing?
