In order to have VPN which uses GRE protocol working with iptables statefull firewall as is configured by PM, i find myself adding nf_conntrack_proto_gre kernel module to autoload at boot time.
Why does PM not load the module automatically?
Why doesn't PM have all modules needed for various protocols tracking loaded by default?
