Hi all, I am new to OpenWRT, been using it for a couple of weeks on RPi 5 with mj22236 images and stumbled upon an issue, maybe someone can help.
I am trying to create a PPtP Client VPN via cli as on the OpenWRT wiki (i know its not secure), just to connect to a neighbor from time to time, but seems the negotiation is failing.
Sun Jan 21 21:34:02 2024 daemon.info pppd[15085]: Plugin pptp.so loaded.
Sun Jan 21 21:34:02 2024 daemon.info pppd[15085]: PPTP plugin version 1.00

Sun Jan 21 21:34:33 2024 daemon.info pppd[15085]: Exit.
I did some troubleshooting and my only clue is this:
root@OpenWrt:~# sysctl net.netfilter.nf_conntrack_helper
sysctl: error: 'net.netfilter.nf_conntrack_helper' is an unknown key
The package kmod-nf-nathelper-extra was already installed, even removed and reinstalled it, but that error is saying otherwise. I previously had a D-link DIR 2660 with the latest OpenWRT 23.0 which had no problem with setting up that PPtP vpn with same config. Comparing the 2, that is how I noticed the sysctl error.
I can confirm the PPtP vpn is working if i connect with a Windows 11 client.
Any help is much appreciated!
Thanks!
