Site-to-Site VPN | Apple Mac OS X Server specs

To display the log path:

$ sudo serveradmin command vpn:command = getLogPaths

The computer will respond with the following output:

vpn:vpnLog = <vpn-log>

Value	Description
<vpn-log>	The location of the VPN service log.
	Default = /var/log/vpnd.log

Site-to-Site VPN

Site-to-site VPN is implemented by the daemon vpnd, which is in turn a wrapper around the racoon daemon and the setkey tool. The racoon daemon negotiates and configures a set of parameters of IPsec. setkey manipulates Security Association Database (SAD) entries as well as Security Policy Database (SPD) entries in the kernel. See the racoon and setkey man pages for more information. racoon also has a webpage: www.kames.com/racoon. You might also find the ipsec man page helpful in getting more information.

Apple provides an interactive s2svpnadmin tool, located in /usr/sbin/, that enables you to configure and set up site-to-site VPN. The s2svpnadmin tool accesses configuration information for the Client Server VPN application in Server Admin. Note that s2svpnadmin does not start the VPN service. You have to start the VPN service separately from Server Admin.

The s2svpnadmin tool can list currently configured site-to-site VPN servers, display their configuration details, add a new configuration, and delete an existing configuration. This tool can be used to configure only a local VPN server, not a remote one. To set up a site-to-site server successfully, you need to configure the two VPN gateway servers at the two sites independently.

s2svpnadmin must be run as root.

Configuring Site-to-Site VPN

To configure a site-to-site VPN, run s2svpnadmin as root and choose the “Configure a new site-to-site server” option. You will need to provide the following information:

ÂA configuration name used to identify the server. This string should not have any spaces in it.

ÂThe external gateway address of the local site.

ÂThe external gateway address of the remote site.
