Ubuntu - IPTables - NAT how to enable PPTP in newer Debian/Ubuntu/Mint Kernels
If NAT is setup then this will work without special forwarding or accepting of GRE packets.
- If you are not blocking outgoing connections and accepting established and related connections.
NOTE: Control connections are established on port 1723 and the actual data is transferred over GRE protocol 47.
Get PPTP and GRE working
modprobe ip_nat_pptp sysctl -w net.netfilter.nf_conntrack_helper=1
NOTE: This loads the ip_nat_pptp module which allows PPTP to work with NAT.
- Then the connection tracking helper is enabled
