I have a CISCO 800 series router for my home network. VPN Tracker is the only solution I know of that allows me to access my home network while I'm travelling in airports and road stops and sitting the back of taxi cabs using my mobile phone to get to my home network. The CISCO VPN client works well if I have access to an ethernet port (wired or wireless). However, the CISCO VPN client will not do a VPN connection via Bluetooth to a mobile phone used as a modem to the internet using GPRS. But VPN Tracker does understand both ethernet ports and the Bluetooth port. With version 4.8 you can have a minimal "easy VPN" configuration set up in the CISCO router and use VPN Tracker on your MacBook to get to your remote network securely.

The company worked with me for over 2 weeks to resolve one problem that was stopping VPN Tracker from working in my setup. It took a little work to get the right dumps and settings to them, but they stuck with me and released version 4.8 that solved the connection problem.

I, personally, think the price they charge for a VPN client, the much better documentation than that provided by CISCO, and the support, is well worth the price.

If you are a travelling "road warrior" and need the most robust VPN client to get back to your home or corporate network, the VPN Tracker is the way to go.
