Chapter 3 Before You Begin

Configuring an ANG-3000/7000

When corporate networks are linked via one or more tunnels, users can utilize applications over these LANs simply by choosing a network- supported program or by using Windows Explorer to find a destination server. Using Aurorean Client to dial up a remote connection is not required.

Remote Aurorean site-to-site connections are set up by first adding a remote ANG to an existing ANG configuration, then adding the tunnel itself. This is done by configuring a user on that server with the following values: an IP address or Fully Qualified Domain Name (FQDN) for the server, a user name and password, and a tunnel protocol (either IPSec or PPTP). These are all the values required to make the connection. We recommend that you enable Intelligent Client Routing on both Aurorean Virtual Network Network Gateways so clients accessing the tunnel remotely or locally can access clients on the far end of the network.

NOTE

Enable at least one routing protocol (RIPv1, RIPv2 or OSPF) on the ANG. Refer to Chapter 3 for instructions.

Refer to “Adding a Remote Server” on page 68 to configure a site-to-site tunnel.

AutoLink Recovery

Auto LinkRecovery (ALR) extends the fault isolation and recovery capabilities of the Aurorean Client to include automatic fail-over to a backup Aurorean Virtual Network system in the event of a service outage or VPN hardware failure.

To support ALR, a second Aurorean Virtual Network system APS, ANG, and RiverMaster management application) is required. The secondary Aurorean Virtual Network system operates in parallel but independently of the primary Aurorean Virtual Network system. Each system must be located on the same corporate network, but can be physically situated at different sites, to support disaster recovery, as shown in Figure 17. For more detailed information, refer to “Viewing Aurorean Alternate Address Information” on page 42.
