VPN: IPSec Tunneling
IPSec tunnels allow a company to pass data between locations over unsecured IP networks such as the public
internet. The company data is secured using 3DES encryption making it unintelligible to other parties that might
be 'eaves dropping' on the traffic. Tunneling can be applied to link offices together or provide workers access to
the office over the internet. All IP Office systems support up to a total of 256K worth of encrypted traffic to
multiple locations. Initially, inter-working is supported only between IP Offices that are connected either directly
on a WAN port or via the LAN using a 3

VPN: Layer 2 Tunneling Protocol
PPP authentication using PAP or CHAP takes place between directly connected routers only. When using a public
IP Network to connect sites this authentication takes place between the customers router and the service
provide router that it is connected to. In some circumstances it is desirable to authenticate between the
customer owned routers, jumping over all the intermediary routers of the service provider's network. Layer 2
Tunneling Protocol allow this to happen by facilitating a two stage authentication, firstly with the service
provider router then the customer router on the remote network.
