I have the following scenario:
- a QNAP in my local network on port 8443 (to thwart at least the bots that attempt to connect to 443)
- myQNAPcloud installed and DDNS enabled
- on the router port forwarding 8443 to the LAN address of the QNAP
support to sort this out)
This works splendidly . The public IP Address is configured for the host-name and all mobile and remote devices and apps (QSYNC) can connect and are happy.
However as soon as I activate an OpenVPN tunnel the whole thing breaks down :
- myQNAPcloud DDNS finds a new public ip address and configures it
- All connections to the DDNS host-name time out
What does work is in the Qsync client (Android) instead of the host-name give the IP-Address. But I would have to change this on every device when my hoster decides to change my public IP.
What I tried is to set a static public IP address in myQNAPcloud GUI but it does not allow me. Probably because it attempts to connect to 443 instead of 8443.
Question: Is there a way to specify the public IP address on the console? Without having myQNAPcloud check connectivity?
