# 关闭VPN时恢复到之前的设置
echo "#!/bin/bash" > /etc/ppp/ip-down.d/pptp-route
echo "ip route replace $(ip route show | grep default | head -n 1)" >> /etc/ppp/ip-down.d/pptp-route
echo "mv /etc/resolv.conf.viry.bk /etc/resolv.conf" >> /etc/ppp/ip-down.d/pptp-route
# 开启VPN时的DNS和路由
cp /etc/resolv.conf /etc/resolv.conf.viry.bk
echo -e "nameserver 172.16.0.1\nnameserver 172.16.1.1" > /etc/resolv.conf
ip route replace default via 172.16.0.1 dev ppp0
