为什么Mac断开OpenVPN后，无法连接到内网，需要renew DHCP

yiqizun

Synology NAS作为VPN Server
Mac版本Tunnelblick作为OpenVPN客户端

每次断开Tunnelblick后，再PING网关就无法到达
ping: sendto: Network is unreachable

PING 192.168.1.138 (192.168.1.138): 56 data bytes
ping: sendto: Network is unreachable
ping: sendto: Network is unreachable
Request timeout for icmp_seq 0
ping: sendto: Network is unreachable
Request timeout for icmp_seq 1
ping: sendto: Network is unreachable
Request timeout for icmp_seq 2
