Plusnet hub zero ports 554 and 7070 permanently open WAN side !

[#1]

A recent scan with fing from an external host shows ports 554 and 7070 open to the WAN.

Scan date: 19:44 22/12/2017
IP Address: xx.xx.xx
State: Online
Hostname: ****

Active services: 2
554/rtsp Real Time Stream Control Protocol
7070/realserver null

The router is configured with a fixed hostname via dyndns and there are no LAN hosts with services on those ports.

My questions are 

1 why is the router opening these ports ?

2 how to disable them from the hub zero ?

[#2]

Do you have any IP cameras on your network? Could be that they're using UPnP to open these ports.

Hi bob

No ip cameras on the network , but there is a youview box , would that open these ports 😐

[#4]

They're not ports I recognise being related to Youview/multicast traffic.
FWIW, I can only see the following at your IP:-
Host is up (0.024s latency).
Not shown: 998 filtered ports
PORT STATE SERVICE
4567/tcp open tram
5222/tcp closed xmpp-client
The first of those is for our TR069 remote management.

Hi Bob,
Thanks for checking this one out. It appears to be related to the use of dynamic DNS in some way. These ports are not showing as open when dynamic DNS is not being used.

[#6]

old post - but I have static IP and these two ports are showing as open when running nmap -Pn against my IP address, since non of my home computers have these ports open (or are running the relevant software) and my router firewall (and the plusnet firewall) blocks all unsolicited traffic (apart from two ports I want open) can someone at Plusnet explain why these two ports are showing as open?

[#7]

They don't show open to me on your IP

I get

Nmap scan report for XXX.plus.com (80.229.X.X)
Host is up (0.035s latency).
Not shown: 998 filtered ports
PORT STATE SERVICE
1 open port removed
4567/tcp open tram

so wonder if you're running it from your local network there's an odd loopback?

Nmap run from my works IP address - added the -Pn to show all open ports...
