VPN / Calendar
The Tiny VPN Island (TVI) is provided for the members and guests of The Society.
When The Society acts as an association, then we will need some means for internal communication.
While there are a lot of free and fancy communication tools "out there", nevertheless we will have an increased need for privacy in our society.
On the one hand, our web site is based on quite elaborate tools like Apache and PHP, so the risk of security leaks is low, even when the web site is reachable via our public address lc-soc-lc.or.at.
On the other hand, we will use quite recent tools for our internal communication, like Web3D Multiuser scenes, so the easiest way to achieve an acceptable level of security, is to employ a VPN.
The VPN is not connected to the Internet (the network traffic is not forwarded/NATed to/from the Internet).
The vServer has a virtual network interface on the address 172.27.224.1, which is a private network address according to RFC 1918, and the vServer will NOT act as IP router. It is a multihomed host.
The Tiny VPN Island is intended to connect up to 10 computers worldwide (concurrently) with a private LAN segment.
It is intended for use with multicast addresses from the local scope range 220.127.116.11 / 16 (a route is preconfigured for these).
