VPN protocols are censored and blocked in China.
PPTP is insecure and is easier to censor, so I’ve removed PPTP client from my router.
OpenVPN is better than PPTP, not only secured, but also much more stable. But traffics are occasionally lost, reset works at most cases.
reset openvpn interface vtun0
But I cannot get ssh access anywhere anytime, so I have to write an script monitor and run ‘reset’ if necessary.
