Supporting Multiple Users

Once your VPN expands to multiple users (or even just yourself connecting from multiple computers

simultaneously), there are certain issues you will have to consider. Primarily, you must ensure that IP

addresses do not conflict. In addition to purely technical considerations, VPN Tracker makes it easy to

distribute pre-configured connections to your users, and prevent the modification of VPN connections

and access to confidential data.

Preventing IP Address Conflicts

If multiple users connect to your DrayTek at the same time, you must ensure that each of them uses a different Local Address in

VPN Tracker by setting an individual Local Address for each of them.

Choosing the Local Address

The Local Address must not be part of the remote network (i.e. the DrayTek’s LAN) and the same Local Address may not be used by

two VPN clients at the same time.

Example: The DrayTek’s LAN in this example is the network 192.168.13.0/24 (=

192.168.13.0/255.255.255.0). Choose an arbitrary private network that is not

part of this network, such as 10.22.13.0/24, and manually assign each user of

the VPN a different IP address from that network to be used as the Local

Address in VPN Tracker.

Advanced Users A more detailed description of the Local Address setting is available in the last chapter of this document.
