The VPN allows you to access in a secure way to Extranet Group Work server and all applications that it hosts. To access to it, your account must have the access rights related to it ("VPN access" box in EGWM or "Relatedness" index in GOsa.



You do not need to install any specific software under windows. Here is the procedure to follow to configure your access:

• In start menu, click on "connections", then "display all connections"
• In the 'network management" section, click on "create a new connection" then on "Next"
• On the "Type of network connection" screen, select "Connection on business network"
• On the "network connection" screen, select "Connection to virtual private network"
• On the "connection name" screen, enter the name of your choice (for example "EGW")
• On the "public network" screen, choose "Do not established the inital connection"
• On the "Selection of VPN server" screen, enter the name or the public Ip address of your Extranet Group Work server and finish wizzard.

In the Virtual Private Network (VPN), you have a new connection, which allows you to launch the VPN.

Test it with your Extranet Group Work login and password (your account must have the VPN access rights).



At the time of connection, Windows sends me the following message "619 error: An unknown error occured"
You probably use a version of kernel, which does not support the VPN protocol used by PPTP (GRE). Use a kernel including the "vpn" keyword (for example 2.6.18.1-vpn-std-ipv4-32).

Note: In the BETA version of EGW, you do have to use the kernel installed by default on the hard disk. Do not use the netboot kernel



Under Linux, we will use pptp-linux

Warning! You must have a kernel having the MPPE support (Microsoft Point-to-Point? Encryption method) to use pptp under linux. You can either recompile your kernel, or upgrade to a 2.6.15 kernel or more which includes the MPPE support by default.

• Install the pptp-linux package, either from the package system of your distribution, or from the pptp-linux web site: http://pptpclient.sourceforge.net/ (Pre-installed packages exist for most of all distributions).You can also download and recompile the sources if necessary.
• Edit the /etc/ppp/chap-secrets file:

• Next, type the following command line to launch the VPN (with root user)

• And that one to stop it

For more details, you can consult directly the pptp-linux web site: http://pptpclient.sourceforge.net/documentation.phtml



You do not need to install any specific software under Mac OS X. Here is the procedure to follow to configure your access:

• Give a name to this configuration (Ovpn for example) and save ;)
