HG612 modem, remote port 8081 OPEN


[link to this post]
 
I have notice port 8081 is open,
when i connect to it externally it is going to a authentication page
"HuaweiHomeGateway"

I assue this is for BT to access the HG612 modem?

I have unlocked the firmware and can firewall it off.... but i do not know the username or password of this!!!

Possibly TR-069 for CWMP http://en.wikipedia.org/wiki/TR-069

Mine is "closed" as I disabled the service on 301.

If you go to the Maintenance/Account tab, there are only 2 accounts defined - admin and user.

Open on WAN or LAN side?

Given the modem does not receive a WAN IP it should not be visible to the internet.

WAN side - there's a PTM running on VLAN 301 for TR-069 which does DHCP.

I presume you superglue the covers onto the diagnostic ports for your car too?

And it will NOT have a public IP address, but a non-routeable private IP, so unless someone hacks into the DSLAM it should not accessible

If people are hacking the DSLAM/MSAN then the admin port on your modem is the least of your worries

Well, it will have the public ip address of the modem on port 8081 as the OP said. I don't think it has anything to do with the DSLAM.

The modem hands a public IP address to the consumers router, are you suggesting that the Openreach FTTC modem also has a public IP address?

Proof?

Yes, it has the same ip address, but you have to specify the port as well to access it from the internet.

The proof is as I said before - there's a PTM service defined on VLAN 301 for TR-069.

So tell me the IP address of a FTTC modem and I'll see if port 8081 is visible
