Ive been looking at a way of securing a web server and several clients. The Clients range from mobile phones to desktops which I want to all connect to a server. Currently I dont have a static IP address at any site (but hopefully will soon), before I start messing around with different types of VPN servers (windows or linux or hardware based). I used to use a service called Hamachi which does what I want, but now isnt free anymore, and doesnt work on mobile phones.
Im wondering if anyone has any suggestions or recommendations of ways of doing this.
