A VPN server can be configured on a Cloud VPS with minimum resources. Below instructions will guide you through installing and configuring PPTP VPN server.
1. Install EPEL Repository
yum -y install epel-release
2. Install Poptop and required packages
yum -y install ppp pptpd net-tools iptables-services
3. Edit /etc/ppp/options.pptpd to make it look like below:
name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
proxyarp
lock
nobsdcomp

novjccomp
nologfd
ms-dns 8.8.8.8
ms-dns 8.8.4.4′
4. Edit /etc/pptpd.conf to look like below:
option /etc/ppp/options.pptpd
logwtmp
localip 10.0.10.1
remoteip 10.0.10.2-254′
5. Enable IP Forwarding:
Run the following command to enable IP forwarding:
echo net.ipv4.ip_forward = 1 >> /etc/sysctl.conf
To verify run the following command.
sysctl -p
You will get output similar to:
net.ipv4.ip_forward = 1
…
net.ipv4.ip_forward should have the value 1.

iptables -t nat -A POSTROUTING -o ens3 -j MASQUERADE
iptables-save
7. Add/Edit PPTP Users:
You can add or edit VPN users by editing /etc/ppp/chap-secrets. It contains user and password pairs in each line.
