We were on MR2 for a short time and moved to MR3. Our WAN IP is dynamic and controlled by DynDNS. That is working fine. I noticed that if you edit the .ovpn file that the XG creates, the last 4 lines remote x.x.x.x 8443, the first one is your WAN IP address, next is your LAN IP address, third is your GuestAP and the fourth is your FQDN. I can't be 100% certain on this yet, but since our WAN IP changes, the first entry becomes invalid when your IP address changes and the fourth one is still valid. I had an issue where I couldn't connect externally and had to either change the first entry to match the fourth entry or remove it all together. Like I said, I'm not 100% sure that this was the reason yet, but opening a discussion to see if anyone else has had this issue. It's a real PITA to change the config file once you've deployed it to a user.
