When you run the pppd debug command, you see the following output from the procedure, How to Diagnose Problems With the PPP Configuration.
Could not determine remote IP address
Cause: The /etc/ppp/peers/peer-name file does not have an IP address for the peer. The peer does not provide an IP address during link negotiation.
Solution: Supply an IP address for the peer on the pppd command line or in /etc/ppp/peers/peer-name by using the following format: :10.0.0.10
CCP data compression has failed and the link is dropped
Cause: The PPP compression configurations of the peers might be in conflict..
Solution: Disable CCP compression by adding the noccp option to /etc/ppp/options on one of the peers.
