微軟windows的PPTP是加密的，不是透明的。見內

 

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.

• 看你弄了個AWS VPN 很興奮，但不幸的是這些 PPTP 等簡易 VPN 早就被破解。。。 -slow_quick- ♂ (691 bytes) () 01/30/2023 postreply 21:47:16

• 你想簡單了，GFW的目的就是block，如果能截留就不會讓你用。PPTP也不是透明的。 -思蘆- ♂ (0 bytes) () 01/31/2023 postreply 08:19:04

• 早有定論。看看新一點的Android，明確說 PPTP or IPSec 是 non-secure VPN -slow_quick- ♂ (46 bytes) () 01/31/2023 postreply 10:04:13

• 安全性差一些，但翻牆已夠用，GFW不是因為其透明而不block。 -思蘆- ♂ (0 bytes) () 01/31/2023 postreply 11:51:00

• 你就是嘴硬。GFW 幹嘛不封 PPTP 但是封 OpenVPN ? 隻是翻牆安全性無所謂 -slow_quick- ♂ (0 bytes) () 01/31/2023 postreply 13:37:22

• 你才嘴硬，我從來沒說GFW不封PPTP，AMS-VPN沒有被封是因為專用，流量小，沒被發現，不是因為是PPTP。 -思蘆- ♂ (157 bytes) () 01/31/2023 postreply 14:07:32
