现在拨号的时候显示：No available tunnel devices found(No such file or directory)

我的ppp.conf
default:
set log Phase tun command
ident user-ppp VERSION (built COMPILATIONDATE)

# Ensure that "device" references the correct serial port
# for your modem. (cuaa0 = COM1, cuaa1 = COM2)

set timeout 180                        # 3 minute idle timer (the default)

set ifaddr 10.0.0.1/0 10.0.0.2/0

然后我把默认路由去掉
route delete 0.0.0.0
然后再拨，没有错误提示了，如下：
[root@no1 /etc/ppp]$ppp -ddial PPPoE
Working in ddial mode
Using interface: tun0

可死活ping不通外网，显示no route to host,怎么回事
