Mac配置路由器教程

记录一下这美好的时刻！
(解决vpn需要走本地所有流量的问题)

直接上脚本，需要的请直接拿走

#!/bin/sh

# ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
#	inet 10.123.456.191 --> 10.123.456.1 netmask 0xffffff00

#ifconfig |grep ppp0 | grep -v grep|awk -F ":" '{print $1}'
#ppp0

#ifconfig |grep inet | grep 10.123.456.1 |grep -v grep|awk '{print $4}'
#10.123.456.1

vpnname=ppp0
vpngateway=10.123.456.1

testname=`ifconfig |grep ppp0 | grep -v grep|awk -F ":" '{print $1}'`
if [ "$testname" = "$vpnname" ]

      echo "get vpn name $testname"

找找看脚本，是不是有问题？ ^_
