I'm trying to get port mapping working on the THG3000 router, without success. Very basic setup, I want to forward a port in the 89XX range from the internet IP of the router to a device on the internal network, same port. Router accepts the configuration just fine, including pressing the "apply" button after adding the port, but trying to connect to it from the internet I get a connection timeout. If I delete the manual port mapping, but enable uPnP on the router and the device in question I also see the port mapping displayed on the port mapping page on the router, but still get the exact same timeout error. Connecting to the device and port from a laptop on my home network works absolutely fine. The firewall on the targetted device isn't enabled, but there is some protection in the software I'm targeting, but pretty sure that's set to allow the connections. Just in case I tried to connect to a different port of the same device, running different software that I'm certain has no protections enabled for source of incoming connections, with the same result.
I've tried pointing the mapping to a different device on my home network, with again the same result.
The machine on the internet I'm connecting from has no firewall on outbound connections and should be able to get to anywhere.
I've spoken to Vodafone support twice now. First time the support agent suggested to me that she was going to do something to the router to enable inbound connections, but that made no difference, then said that she was doing something on the Vodafone network side to allow this, but that would take up to 24 hours. 2 days later still no difference so I contacted support again. This one tried to convince me that Vodafone does not support port mapping, despite their documentation clearly covering this, and then suggested that I should use guest WiFi (no, I've no idea why either, I don't think he understood what port mapping is). He also seemed to suggest that I should get a 3rd party router if I wanted to use port mapping, but given his confusion level in general during the discussion I'm reluctant to spend time and money getting another router if the problem could be in the Vodafone network rather than the router, plus I don't see why the THG3000 can't do this itself.
I'm on the CityFibre network with Vodafone, not sure if that's relevant or not.
Does anyone have port mapping working successfully with the THG3000? If so can you let me know your firmware version, in case this is a bug in the version I have, 19.4.0551-3261126?
Thanks
