Comment (by anonymous):

 Thanks so much for the reply.
 I think the connection was set up correctly is based on the log.  It shows
 "Initialization Sequence Completed"
 But if I type ifconfig, the tun0 nic was up but without IP address. After
 10 seconds, the daemon restarted with "Inactivity timeout (--ping-
 restart), restarting"
 I used the same conf file on DD-WRT, everything works fine.

 ifconfig returns
 tun0      Link encap:UNSPEC  HWaddr
 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
