Description of problem: In Fedora 36, I had an issue with PPTP VPN and had to run: sudo sysctl net.netfilter.nf_conntrack_helper=1 then echo net.netfilter.nf_conntrack_helper=1 | sudo tee /etc/sysctl.d/98-nf_conntrack.conf https://ask.fedoraproject.org/t/pptp-vpn-blocked-by-firewall/8097 I upgraded to Fedora 37 and PPTP VPN no longer works. nf_contract_helper=1 is no longer valid. The PPTP is being blocked and I can find no reason why. All troubleshooting of nmcli and firewall yields nothing. Version-Release number of selected component (if applicable): 6.0.12-300.fc37.x86_64 How reproducible: can't vpn Steps to Reproduce: 1. Have working PPTP VPN in Fedora 36 via https://ask.fedoraproject.org/t/pptp-vpn-blocked-by-firewall/8097 2. Upgrade to Fedora 37 3. Check all VPN and IP settings on both ends 4. Realize the problem is Fedora being broken again because I had problems with my OS the first time and 37 changed how to unlock PPTP without giving us a memo. Actual results: VPN via PPTP Expected results: actually connect and not being told PPTP is unsecure Additional info:
Was there a change to net.netfilter from 36 to 37? Any dependencies or code changes to make this old config setting irrelevant?
changed compontent to libnetfilter_conntrack. Not sure if it is that component or the kernel itself

Problem persists in 38. Older PPTP connections will not function since the work around for Fedora 36. It's a shame nobody has fixed this.

This problem still persists in Fedora 38 and 39. PPTP tunnels are not working, but they work in Windows so we have a valid PPTP config.
