Ill have a go with a container tomorrow - thanks - but I suspect I have a more fundamental issue to solve - see below…
I have just been enabling/disabling upnp in the router and QNAS without any effect - I have found out that when I run the port forwarding test on the QNAS it all fails.
I have also noticed that the WAN ip address on the QNAS / listed on myQNAPcloud is different to the WAN IP address(s) on my router
(so I have 4 different IP addresses -
WAN IP on the Router 100.99.xxx.xxx )*
Router IP 100.99.zzz.zzz )*
QNAS WAN IP / myQNAPcloud 149.22.xxx.xxx
QNAS internal network IP 168.192.4.200 - set via DHCP
- Dont understand the difference - my last router only had 1 WAN IP
