I have a  Cisco SRP521W connected to XNet via a fibre modem to a UFB connection. This is a broadband and VoIP service.

Ever since I joined the service and started using the modem, the admin password seems to get reset about a minute or two after connecting it to the WAN connection.

I reset it to factory defaults with the WAN connection disconnected. I can then connect using the default admin and cisco user passwords. I then change these both to another password and connect the router WAN connection.

A few minutes later, the modem makes a click sound and I can't connect with the admin login anymore. The cisco user password is still the one I changed it to.

Does anyone know why and how this is happening? I have also disabled remote management.

It is being "auto provisioned" by Xnet's VFX (phone) service.  You will still be able to access most of the router settings, but not the "Voice" section.  This is a deliberate policy on Xnet's part, to ensure that the phone service works properly.  I also have an SRP521W and don't have any problem configuring any of the settings I need to access.

Thanks for the quick reply. I thought as much.

I'm curious how they manage to gain access without having the username and password, after a factory reset. Is a certificate based login?

Correct, *most* items are still available to the Cisco user, but not all.

Some items, for example the web interface https/http control "management" interface has been hidden, as has the remote debug and "Cisco VPN" server and cisco user pages, SIP etc.

I want to have full control of the device, e.g to be able to configure the VPN LAN to LAN tunnels and other VPN functionality. I understand they don't want the voice side to be changed.

Do you know if XNet will disable this policy on this router?

If you want full access you'll need to change your account to an OpenVFX account. You will also need to fully configure all of your voice settings in the router manually before your phone will work because these will no longer be configured automatically.

The router is updated because it has a provisioning rule in the provisioning settings which points to the WxC provisioning server.

The 521 also doesn't contain a "VPN sever" it can only connect to a VPN.

I'll look into the OpenVFX option - thanks for the suggestion.

For info, the SRP521W firmware version 1.01.26 has a "Cisco VPN Server" under "VPN" which seems to be a Remote VPN type option. This wasn't in the 1.01.24 version.

Within a minute or so after configuring the WAN interface, the router was reset again.

When I could connect again, the firmware version was downgraded back to 1.01.24 again.
I re-ran the firmware upgrade a bit later and the router again reset and had the admin password changed as now expected. However, the firmware stayed at the newer version.

The VPN Server configuration setting is still available. I still plan to test it.
