本人通过pppd2.4.4在linux下对TD-SCDMA模块拨号，按照defaultroute获取IP信息
ppp0 Link encap:Point-Point Protocol

我现在想把Gateway修改成10.233.25.191，如何做呢？
------解决方案--------------------------------------------------------
先route del -net 192.168.0.1 netmask 255.255.255.255
然后route add -net 192.168.0.1 gw 10.233.25.191 netmask 255.255.255.255 dev ppp0
