1000 network ports open on the external address?
1000 network ports open on the external address?
We have just received a report from out pen-testers, who tell us that we have something like 1000 network ports open on our external address; I assume this means our router has something listening on those ports, although I can't rule out that there is some additional hardware between our router and the ISP. Is it to be expected that the TL-ER7206 has those ports open, and if so, what can I do to close them?

Hi @j4nd3r53n
Case closed due to no further replies in ticket.
Update to anyone who is looking for help on the similar issue:
Current situation: dev did not reproduce the same issue with his backup. Consider this a problem with the user environment, not the system fault. Ask for remote debug but no further replies.

Hi @j4nd3r53n
Thanks for posting in our business forum.
1. What software do you get your report?
2. What ports are open? Screenshot, please?
3. External address is referring to the WAN IP, the real public IP address? What's displayed on the WAN interface on the router?
Please ask your "partner" to fact-check if this is an on-going connection which is expected to be normal or if they are left to be open like port forwarding.
Please mosaic your sensitive information. Here is a list of information considered sensitive:
1. Public IP address on your WAN if your WAN is.
2. Real MAC address of your device.
3. Your personal information including address, domain name, and credentials.
For troubleshooting purposes, when a WAN IP is needed, please leave some values visible for identification.

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.

I am not worried so far based on your description. Unless something is new or clearly wrong.
You can mention me if you can show me the WAN IP as a public one. Still mosaic some parts. And the nmap test result.
Make sure you include a picture of "ip addr" on your Linux. So I can understand where this test happens.

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).

Hi @j4nd3r53n
Thanks for posting in our business forum.
Please remove your IP addresses in the last reply.
About this, you don't have any port forwarding or port triggering? Firmware is 1.4.1, just for confirmation.

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

Have informed the dev team to take a look at this. Waiting for further instrcutions.

We have just received a report from out pen-testers, who tell us that we have something like 1000 network ports open on our external address; I assume this means our router has something listening on those ports, although I can't rule out that there is some additional hardware between our router and the ISP. Is it to be expected that the TL-ER7206 has those ports open, and if so, what can I do to close them?
Dev team did not replicate this. Using nmap only found two available ports.
So, we assume that there is something special in your network.
Are you okay to provide your backup file to us? Dev will import and test again.
If you are okay to provide the file, we will do this privately. Let me know if you agree with this proposal.

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?

No. I need the backup of your controller. Not the .csv file.
Ticket ID will be sent to you later and same as the email.
