微软windows的PPTP是加密的，不是透明的。见内

 

The PPTP specification does not describe encryption or authentication features and relies on the Point-to-Point Protocol being tunneled to implement security functionality. However, the most common PPTP implementation shipping with the Microsoft Windows product families implements various levels of authentication and encryption natively as standard features of the Windows PPTP stack. The intended use of this protocol is to provide security levels and remote access levels comparable with typical VPN products.

• 看你弄了个AWS VPN 很兴奋，但不幸的是这些 PPTP 等简易 VPN 早就被破解。。。 -slow_quick- ♂ (691 bytes) () 01/30/2023 postreply 21:47:16

• 你想简单了，GFW的目的就是block，如果能截留就不会让你用。PPTP也不是透明的。 -思芦- ♂ (0 bytes) () 01/31/2023 postreply 08:19:04

• 早有定论。看看新一点的Android，明确说 PPTP or IPSec 是 non-secure VPN -slow_quick- ♂ (46 bytes) () 01/31/2023 postreply 10:04:13

• 安全性差一些，但翻墙已够用，GFW不是因为其透明而不block。 -思芦- ♂ (0 bytes) () 01/31/2023 postreply 11:51:00

• 你就是嘴硬。GFW 干嘛不封 PPTP 但是封 OpenVPN ? 只是翻墙安全性无所谓 -slow_quick- ♂ (0 bytes) () 01/31/2023 postreply 13:37:22

• 你才嘴硬，我从来没说GFW不封PPTP，AMS-VPN没有被封是因为专用，流量小，没被发现，不是因为是PPTP。 -思芦- ♂ (157 bytes) () 01/31/2023 postreply 14:07:32
