Mine is turned off as I said earlier. But anyone can use Shields-Up on http://grc.com to see for themselves.

Have tried to access the port over the internet on a BT Infinity line and it is not accessible.

Other providers have done things like only allow certain IP addresses to access the TR-069 ports, so expect similar for Openreach.

grc is not infalliable too, a lot of routers detect the initial probes and then shut down ports, even if they were open as part of DoS protection.

Perhaps more people would like to PM the public IP address so I can peek away.

People have remembered to look into this when NOT using an Ethernet router that maybe has these ports open? e.g. HomeHub3

I just had a infinity2 install last week, and noticed BT support in India can look what you've changed in the Home Hub, like SSID,etc. after that shock, I tested the ports, and found 8081 open.

From remote windows server, I got tried to see if I can login to my locked modem, and it did come up with the remote login in Chrome:

Authentication Required

The server 86.167.xxx.xxx:8081 requires a username and password. The server says: HuaweiHomeGateway.

User Name:

Password:


So it's open to anyone not just BT.
Does unlocking the modem and switching it to ATM mode close this port?

You don't want ATM mode, it should be PTM.

But if you change the firewall setting from BT to Custom or something, that should block the remote ports.

yes, my mistake, infinity2 is VDSL2 based and supports the Packet Transfer Mode.

I've not unlocked the modem yet,but looking at the manual for the modem, it supports full router mode with NAT, DHCPd, firewall,etc,

Is this is true in the unlocked modem firmware?
if so, then you can bypass the homehub3, and plug direct to a Gbit switch.

Yes, you can use the HG612 as a router and skip the HH3.
