VPN Lite
VPN lite is a service provided by Telkom to allow you to connect multiple sites (nodes)
together as if they were on the same physical LAN. These sites can be physically anywhere
on the Telkom ADSL network, but will from a data point of view appear as if they are all on
the same physical site. This will allow the use of a common server and server based
applications, direct printing to local printers, and sharing of data without affecting your
internet cap.
Before you configure this, you will need to subscribe to the function, and be provided with a
set of PPP username and password as well as IP address and netmask for each node.
The VPN lite function is configured exactly the same as you would configure an internet PPP
connection, except that there is also a set of rules that must be added to the routing table to
allow all nodes to be able to talk to each other. This is essentially that all of the non-internet
routable IP address ranges (for example 10.x.x.x, 192.168.x.x), except the local network are
router over the WPN lite PPP connection. There are also some changes required to the
firewall.
Fortunately, we have provided a utility to make this configuration easier.
