Hi  @Clive_A 

1: I used nmap from the (linux) command line, connected via my mobile hotspot, so I would access the external IP address from the outside.

2: I can provide a list of ports as a text file (1009 lines); it would be awkward and not all that informative to turn it into an image. The open port numbers seem to cover much of the range from 1 to 1000 with some holes, and then what looks like almost random ports from 1000 to 65389, which make no sense to me.

3: The external address is what is visible to the public; I initially assumed that this would be the address of the WAN port of the router, but in Omada it looks like it has the same address as the LAN IP address - but maybe I'm getting this wrong:

I've left the public IP address visible, since it is clearly an internal address.

I had a look in our network rack, and I realise there is at least one piece of hardware between the router and the real world: an Aruba 2530 managed switch, which of course isn't managed by Omada - and there may be other hardware between that and the ISP, which is shared between all the offices in the building. We are working towards getting our own ISP, so those will be going away., and perhaps the issue will resolve itself in time.

Can I assume that the TP-Link router isn't likely to be the guilty party in this context?

EDIT

Actually, I realised that I was looking at the wrong screen  - the tab labeled WAN actually shows the correct, external address, so the ports I detect do appear to be open on the router itself. However, when I try to connect to them, eg with 'telnet x.x.x.x [port]' or with netcat, there seems to be no communication at all.

Hi  @Clive_A 

So, here's the screenshot of the WAN setup:

And my IP address when on the hotspot:

The nmap command is simply nmap 83.xxx.xxx.76 and the output (truncated, since the inter):

# nmap 83.xxx.xxx.76       
Starting Nmap 7.93 ( ... ) at 2024-03-27 16:02 UTC
Nmap scan report for 83.xxx.xxx.76
Host is up (0.063s latency).

Nmap done: 1 IP address (1 host up) scanned in 21.87 seconds

Hi   @Clive_A 

IP addresses have been masked, thank you for reminding me.

No, we don't have any port forwarding or -triggering; and yes, we have upgraded to 1.4.1 recently.

Hi   @Clive_A 

Yes, I can share that file with you; I had a look in the manual I've got ("User Guide - Omada SDN Controller V5.9"), which tells me to go to Settings in the global view, which should take me to Maintenance -> Backup & Restore -> Backup, but the only option I see is Export, where I can export a csv file. Is that the one you need?
