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

This entry will show you on how to create a PPTP server in Arch.

We installed pptpd with :

pacman  -S pptpd 

Now, edit the file /etc/pptpd.conf

option /etc/ppp/pptpd-options
localip 172.16.36.1
remoteip 172.16.36.2-254

Now, edit the file /etc/ppp/pptpd-options


name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
proxyarp
lock
nobsdcomp
novj
novjccomp
nologfd
ms-dns 8.8.8.8
ms-dns 8.8.4.4

Now we must add my users & passwords in "/etc/ppp/chap-secrets"

<username>     pptpd     <password>   *

Now, enable IP Forwarding by editing "/etc/sysctl.conf"

net.ipv4.ip_forward=1

Now apply the changes made to sysctl.conf

# sysctl -p

Configure your iptables settings to enable access for PPTP Clients

iptables -A INPUT -i ppp+ -j ACCEPT
iptables -A OUTPUT -o ppp+ -j ACCEPT

iptables -A INPUT -p tcp --dport 1723 -j ACCEPT
iptables -A INPUT -p 47 -j ACCEPT
iptables -A OUTPUT -p 47 -j ACCEPT

iptables -F FORWARD
iptables -A FORWARD -j ACCEPT

iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE
iptables -A POSTROUTING -t nat -o ppp+ -j MASQUERADE

Now save the new iptables rules with:

# rc.d save iptables

Read Iptables for more information.

Now you can start your PPTP Server by this command and enjoy

# rc.d start pptpd

You can use this script to auto install pptpd server
