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.
