Can't add PPTP VPN Connection

I installed Lubuntu 19.10 for first time and I can’t add a pptp vpn connection. I used to add it from network connections on peppermint os 10 or linux mint 19.3

you need to install addon network-manager-pptp
i can add but there is no way to connect, very odd

i couldn’t figure out why the pptp doesn’t work with network manager in lubuntu 19.10, but i have managed to get it done by manually configure my pptp connection

Here you go - https://wiki.ubuntu.org.cn/UbuntuHelp:VPNClient

once connected, do following
sudo route
sudo route del default gw <LOCAL_GATEWAY>
sudo route add default gw <VPN_GATEWAY​>
sudo vim /etc/resolv.conf
nameserver <VPN_GATEWAY>

then all traffic will go through remote pptp server

I think you also want network-manager-pptp-gnome.
