Hi,
I have a SRP527-U running 1.2.6 Firmware.
I have a supported USB Stick 3G and it's working fine. I am using the Voice Module of the SRP for Phone services.
The problem I face is that Mobile data is quite expensive, therefore I'd like to ensure that under a failure scenario (that is, the ADSL Link is down) that only the Voice Module gets Internet access via the 3G connection, but standard Web Browsing etc for the end users fails.
Is this something that's possible? The Source IP address of the Voice Module isn't obvious to me - is it always the active WAN IP address? Is it an Internal IP that's NAT'd?
Is what I'm trying to do even possible, or is this outside the capabilities of this device?
Kind Regards,
Tim
