Enable IPV6 support in PPP for the local link between the DTE (processor) and DCE (modem).
There are some modems which do not support the IPV6 addressing in the local link.
If they are requested for IPV6CP negotiation, they may time out.
This would in turn fail the configuration for the whole link.
If your modem is not responding correctly to PPP Phase Network, try to disable IPV6 support.
