The eth0,eth1 and eth2 are all normal network interface card,they all
connect to a PC.No matter what they connect ,the problem is the same.
When I read the 'man pppd',I found this words,is this be the problem?

man pppd
<local_IP_address>:<remote_IP_address>
              Set the local and/or remote interface IP addresses. 
Either one may be omitted.   The
              IP  addresses  can  be  specified  with  a host name or
in decimal dot notation (e.g.
              150.234.56.78).  The default local address is the
(first) IP address  of  the  system
              (unless  the  noipdefault option is given).
