pptpd
=====
The Point-to-Point Tunneling Protocol is a method for implementing virtual private networks.
PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.

> WARNING: YOU NEED TO REBOOT IF CONTAINER RESTARTED.
You need to config firewall:
You must open the following ports:
- To allow PPTP tunnel maintenance traffic, open `1723/tcp`.
- To allow PPTP tunneled data to pass through router, open `Protocol 47`.
## firewall
If you use `net: host` for networking:
```
$ vim /etc/defautl/ufw
# DEFAULT_FORWARD_POLICY="ACCEPT"
$ ufw reload
$ ufw allow 1723
$ iptables -t nat -A POSTROUTING -s 192.168.127.0/24 -j MASQUERADE
```
- To let PPTP tunnel maintenance traffic, `allow port 1723/tcp`.
- To let PPTP tunneled data to pass through router, `allow proto gre`.
- Set `net.ipv4.ip_forward=1`
- Set `DEFAULT_FORWARD_POLICY=ACCEPT`
