Three questions are answered in the configuration of VPN connections:
- Between which VPN gateways (remote stations) is the connection established?
- What security parameters are used to secure the VPN tunnel between the two gateways?
- Which networks or computers can intercommunicate via these tunnels?
Note: This section introduces the basic considerations for configuring VPN connections.
Considered first of all is the simple connection of two local networks.
Special cases such as dialling in to LANs with individual computers (RAS)
or the connection of structured networks will be covered subsequently.
