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.
