The Gnome NetworkManager has pluggable support for VPN software, including Cisco compatible VPNs (using vpnc), openvpn, and Point-to-Point Tunneling Protocol (PPTP). You need to simply install the NetworkManager VPN plugin and configure the user’s machines with the VPN’s settings. The first time they connect, the user will be asked for their passwords.


The Add tab is greyed out when required plugins are not installed for Gnome NetworkManager. The following plugins should be installed under RHEL / Fedora / CentOS / Scientific Linux / Red Hat Enterprise Linux desktop systems:

  1. NetworkManager-openvpn : NetworkManager VPN plugin for OpenVPN
  2. NetworkManager-pptp : NetworkManager VPN plugin for pptp
  3. NetworkManager-vpnc : NetworkManager VPN plugin for vpnc

To install all of the above plugins use the yum command as follows:
# yum install NetworkManager-vpnc NetworkManager-pptp NetworkManager-openvpn

Now, you can add vpn connection to your system using NetworkManager itself. You may need to restart the NetworkManager as follows:
# /etc/init.d/network-manager restart
