Configuring Access Point Security
The access point allows up to 25 VPN tunnels to either a VPN endpoint or to another access point. VPN
tunnels allow all traffic on a local subnet to route securely through an IPSec tunnel to a private network.
A VPN port is a virtual port which handles tunneled traffic. VPN is also supported with the Access
Point's new WWAN feature. For more information, see
When connecting to another site using a VPN, the traffic is encrypted so if anyone intercepts the traffic,
they cannot see what it is unless they can break the encryption. The traffic is encrypted from your
computer through the network to the VPN. At that point the traffic is decrypted.
Use the VPN screen to add and remove VPN tunnels. To configure an existing VPN tunnel, select it
from the list in the VPN Tunnels field. The selected tunnel's configuration displays in a VPN Tunnel
Config field.
To configure a VPN tunnel on the access point:
1 Select Network Configuration > WAN > VPN from the access point menu tree.
2 Use the VPN Tunnels field to add or delete a tunnel to the list of available tunnels, list tunnel
network address information and display key exchange information for each tunnel.
