VPN Tracker 4.5
. VPN Tracker 4.5 is the only VPN Client for Mac OS X that supports SonicWall's DHCP over IPsec, providing a direct download of the VPN-configuration from the SonicWALL VPN-gateway which eliminates the need to manually configure each computer. VPN Tracker also supports Client Provisioning via "Mode-Config," used by a variety of VPN-gateway manufacturers like Cisco and Juniper. Both methods serve to automatically distribute the needed configuration-parameters, such as IP address, DNS-information, etc., from the VPN Gateway to the client. VPN Tracker 4.5 is available for $200 and requires Mac OS X 10.2.5 or later.
