Description:
PPTP client VPN connection throw “LCP received ProtRej for unsupported protocol” error message after 30 minutes connection
RouterOS version:
v6.23.1 on X86
How to reproduce:
Create a PPTP client VPN connection and connect to any paid PPTP VPN service. After seeing any video online continuously for around 30 minutes, the video will stop, Winbox Interface window will show no activity on the PPTP client connection, but it is still in connected status.
Log will show this:
I can reproduce this on every single paid VPN service provider that offer PPTP connection. It seems it will only happen when you use the VPN for watching video or large data download continuously for more than 30 mins.
