IPLink 3210 Series Getting Started Guide
The corporate multi-function application carries two types of traffic between each remote office and corpo-
rate's central office:
•
Private corporate traffic (the intranet/extranet)
•
Internet traffic
The service provider offers a Frame Relay network for access, so both the private corporate traffic and the Inter-
net traffic is transported over a Frame Relay PVC with one DLCI. The corporate traffic is transported within
IPSec VPN that is in the Frame Relay PVC. The separation of corporation and Internet traffic is managed by
using an ACL using IP addresses as the watershed.
To configure this application, you must configure the following features:
•
A serial Frame Relay link as the WAN service which will carry both private corporate traffic and public
Internet traffic
•
An IPSec VPN for private corporate traffic
•
An ACL to distinguish between the two types of traffic so only the private corporate traffic is carried over
the VPN.
