How to setup pptp vpn on linux?

Hello Saonbd

• Please ensure the installation of PPTP daemon (server) at first place, and you can use apt-get for installing the same

apt-get install pptpd

• When done, proceed to create new user account for the VPN server by editing the chap-secrets file. You can use the editor of your choice, preferably Nano.

nano -w /etc/ppp/chap-secrets

• In order to add each user in new line

yourusername pptpd yourpassword *

• Then you need to configure localip/remoteip assignment on pptpd.conf

nano -w /etc/pptpd.conf

localip 192.xxx.xxx.xxx

remoteip 192.xxx.xxx.xxx,192.xxx.xxx.xxx

• Then you need to enable IP forwarding by editing sysctl.conf file

nano -w /etc/sysctl.conf

• Now, uncomment the following line

net.ipv4.ip_forward=1

• Then you would save the file & re-load configuration

sysctl -p

• Then you need to edit rc.local file for ip table rule

nano -w /etc/rc.local

• Add the following lines exactly above exit line. (eth9 is my public Ethernet port, modify as required)

/sbin/iptables -t nat -A POSTROUTING -s 192.168.111.0/24 -o eth9 -j MASQUERADE

/sbin/iptables -I FORWARD -p tcp -syn -i ppp+ -j TCPMSS -set-mss 1356

• Lastly, you need to define the DNS to use with your pptpd. Preferably, Open DNS or Google Public DNS

nano -w /etc/ppp/options

• Uncomment the entries with ms-dns 192.168.1.1 and 192.168.1.2 then replace the IP with Google Public DNS IPs so it look like this

ms-dns 8.8.8.8

ms-dns 8.8.4.4

Setup would complete. Then please reboot your server and test connectivity using PPTPD.

Hope this helps !
