一般來說很多VPN 連上去以後,
就不能連到外網,
這個教學是為了讓我自己不要忘記如何設定,
連上VPN 以後又可以連到外網同時工作。
如果有任何問題可以寄Mail 給我,歡迎大家討論。
一. 先將原本的 routing 印出,等等會用到
C:\Documents and Settings\Administrator>netstat -r

二.連接上 VPN
三.將連接上VPN 後的 routing 印出
C:\Documents and Settings\Administrator>netstat -r

Persistent Routes:
None
C:\Documents and Settings\Administrator>
四. 先刪除全部的 default route
C:\Documents and Settings\Administrator>route DELETE 0.0.0.0
C:\Documents and Settings\Administrator>
五. 增加對外網路的 default route ( 可參考第一次的 routing , 每個人的對外 gateway 都不同請自行判斷 )
C:\Documents and Settings\Administrator>route add 0.0.0.0 MASK 0.0.0.0 192.168.1
23.254 METRIC 25
C:\Documents and Settings\Administrator>
六.設定 VPN subnet 的 default route ( 可參考第二次的 routing , 每個人的vpn取得的ip與對外 gateway 都可能不同,請自行判斷 )
C:\Documents and Settings\Administrator>route add 10.1.0.0 MASK 255.255.0.0 10.1
.11.217 METRIC 1
C:\Documents and Settings\Administrator>
七. 應該可以同時對外又可以連VPN,可以快樂使用。
