pppd拔号完不能上网的问题

本人对linux不熟悉，这几天在android下面linux kernel里面用pppd ttys1拔完号(cmnet)，已经显示
I/pppd ( 216): local IP address 10.194.216.202
I/pppd ( 216): remote IP address 192.168.0.1

然后route显示:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.1 * 255.255.255.255 UH 0 0 0 ppp0

ifconfig显示:
lo Link encap:Local Loopback

UP LOOPBACK RUNNING MTU:16436 Metric:1

ppp0 Link encap:Point-to-Point Protocol

ping 202.108.22.142（www.baidu.com）也不通
请教各位有可能是什么原因?
在网上说是必须设置route中的gateway,不知道在linux下面怎么设置gateway?
