required.

2. Openvpn

Use `yum install openvpn`, `dnf install openvpn` or `apt-get install openvpn` as
required.

Preparatory Steps
=================

For server setup
----------------

1. Enable IP Forwarding

$ echo 'net.ipv4.ip_forward = 1' >> /etc/sysctl.conf
$ sysctl -p

2. Enable traffic via internet

$ iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
$ iptables-save

3. Edit sample/server.conf (Optional)

Edit server.conf to change things like port (line 1), logfile name (line 10 12),
log verbosity (line 11) and server config (line 4).

For client setup
----------------

1. Edit sample/client.ovpn

Edit client.ovpn to set verbosity(line 6) and remote ip and port (line 4).

Make sure server and client have same ports.
