- Changing network mode to 'Host'
- Changing back to NAT (as I had to create the container as 'NAT', this being the only way to specify a MAC address).
- Changing back to 'Bridge' with same IP as QNAP.
- I even searched for a container configuration file (and failed to find it)...  It would be so much easier to edit such a file, if it exists.

Everything either has no effect or makes it worse, leaving me to work out how to recover.

This is definitely a QNAP support problem. The containers work fine running in Debian and CentOS on my end. I have no familiarity with QNAP, but I would suggest that if it is possible to just run the containers from the command line using the Docker executable.


--- Code: ---docker run -d \
    --name=jrivermc26 \
    --net=bridge \
    --restart=always \
    --mac-address=ed:e8:60:2d:65:c1 \
    -p 5800:5800 \
    -p 5900:5900 \
    -p 52199:52199 \
    -p 52101:52101 \
    -p 52100:52100 \
    -p 1900:1900/udp \
    -v config:/config:rw \
    -v /path/to/music:/data/music:rw \
    -e VNC_PASSWORD=12345 \
    shiomax/jrivermc26
--- End code ---

It seems that whatever software they have built on top of Docker is broken.

Scobie:
My main setup is MC26 running on the QNAP Container Station, and can access from the internet using this config:

Network Mode: Bridge
Use Interface: Adapter 1( Virtual Switch 1)
Static IP (on local network)
Assigned Mac Address (can be anything)

On my router
Forward 52199 to the Static Container Address on TCP/UDP

There are only 2 differences on my system:
- "TCP" not "TCP/UDP".  I have changed this and it made no difference...
- I'm using "Virtual Switch 3" - probably due to previous attempts.  The other 2 are not associated with a physical adapter.

"Virtual Switch 3" has the (static) IP address of the QNAP NAS.

Robad:
You're not going to believe this...

I just tried connecting from my phone.  The Access Key has been changed so I edited the server in JRemote.  I noticed that there was a field for "Global IP", which was close to the IP address from 'www.whatsmyip.org'.  So I edited it to make it the same.  I then disabled wifi on the phone and succeeded in connecting!

I have no idea of the relevance of this.  Maybe next time I'm allocated a different external IP address it will stop working (despite the Access Key claiming to cope with this).

Test still fails though...

Scobie:
If at all possible try and get a static IP from your ISP, it makes external access a lot easier, but it does look like your MC/Container setup is correct given that it did work.

Even so, I think I'm right in saying - happy to be corrected - that as long as your external IP is accessible (i.e. not double NAT'd or something) then if the key is correct JRemote should be able to maintain the correct address.
