IP Tunnels

Can you tell us exactly what you are trying to accomplish?

An IP tunnel is a way to connect is a way to create an encrypted connection over the public Internet either between either a single computer and a remote site, or two remote sites.

This is to allow either connectivity to hosts/services that you don't want to give general access over the Internet.  Say you have a file server for your company that you want employees to access from their home.  You really don't want to put the file server "live" on the Internet, so you setup a VPN server that allows employees to connect to it and then it routes traffic between the file server and the employee's home computer.

I'm looking to connect a cradlepoint 600b router where i work and have it setup on a private APN. But connect to it with devices.....I'm wondering how i can acheive it with using tunnels

Thanks for response...

In that case, try OPEN VPN.

Accepting own comment as other comments not fulfilling criteria.

It difficult to provide a meaningful sample, as each device/software has their own way of setting up tunnels.

The use of a tunnel was explained, if its not clear, then ask for clarification.

Also not sure what you mean by "APN", can you please explain what that is in reference too?
