Amrita© VPN can be used to connect two private networks through a public network such as the Internet. It requires only one end to have a direct Internet connection preferably with a permanent public IP address. The other end could be connected to the Internet via a masquerading router.
A summary of important features include:
- Easy to configure and install. No kernel modifications. Works at application-level. Uses SSL (OpenSSL library) for strong encryption and authentication.
- Fast packet relay.
- Comes with a tool (amvpn-keytool) that makes key generation/management quite easy.
- Allows connecting through an intermediate proxy.
- Allows configurable automatic reconnecting after a connection break.
- Needs root privileges only during the initialization time, afterwards runs without root privileges.
- Multiple instances can be easily set up and managed.
- Events such as connects, disconnects and modification of key/cert files can be notified to the admin via email.
- Has ability to transparently forward Microsoft networking messages to the remote network. This enables the two networks to see each other's machines in the 'Network Neighborhood'. Keep alive option to quickly detect connection breaks, allowing fast reconnects. The tunnel can be discontinued by killing the amvpn process.
