not explicitly forwarding any ports - I am using a BT Home Hub 5 with upnp enabled.
However, it looks like I have fixed it.
I looked in the BT Home Hub Event log - it was forwarding the following:
| 07:17:12, 30 Apr. | (33988.450000) Port forwarding rule added via UPnP/TR064. Protocol: TCP, external ports: any->22857, internal ports: 22857, internal client: 192.168.1.71 |
| 07:17:08, 30 Apr. | (33984.070000) Port forwarding rule added via UPnP/TR064. Protocol: UDP, external ports: any->22857, internal ports: 22857, internal client: 192.168.1.71 |
I disabled “Remote Access” in the My Cloud Settings/Cloud Access settings and then re-enabled and the Event log showed:
| 21:46:29, 30 Apr. | (86143.210000) Port forwarding rule added via UPnP/TR064. Protocol: TCP, external ports: any->9444, internal ports: 443, internal client: 192.168.1.77 |
| 21:46:24, 30 Apr. | (86138.690000) Port forwarding rule added via UPnP/TR064. Protocol: TCP, external ports: any->9091, internal ports: 80, internal client: 192.168.1.77 |
So it looks like before I did this, the ports being forwarded by UPNP were a bit screwed but turning remote access off/on has reset it to correctly forward to the right 443/80 internal ports!!
Hurrah!
