IPSecuritas is the most advanced, yet free IPSec client for Mac OS X. It supports virtually every available IPSec compliant firewall, allowing you to connect safely to your office or home network from any location on earth.
IPSecuritas interoperates with a large and daily growing number of VPN devices, including devices from popular manufacturers such as Cisco, Zyxel, Netgear and more. IPSecuritas is known to work with devices from the following manufacturers: BEC Technologies, Check Point, Clavister, Collax, Cyberguard, DrayTek Vigor, Openswan (Linux), GTA Firewalls, Mako Networks, Netgear, NetScreen, PGPnet, SnapGear, SonicWALL, SmoothWall, WatchGuard Firebox, Windows 2000/XP, Zyxel ZyWALL, Cisco PIX, Kame (Free/Open/NetBSD, MacOS X) and many more.
Worked on all macOS versions up to Monterey.However, support is non-existent. I've never ever received a reply when I asked a question.
So far, so good... IPSecuritas seems to be doing a great job on my new Mac Mini under Lion. Control interface could be a little better; but, all in all, very easy to set up.Stay Tuned.Mike
