AcerRouter 700 Series User Guide 1-6
Similarly, when a remote site requests the creation of a tunnel, the AcerRouter 700
will search for an appropriate tunnel profile matching the setup request. Once the
tunnel is established, the remote site will initiate a user session to flow through that
tunnel and the AcerRouter 700 will search for a matching VPN Connection Profile
matching the request. Once found, the AcerRouter 700 will use the information in the
matched profile to authenticate the incoming "call", after which data transfer can
begin.
Tunnels allow IP, IPX and Bridging traffic to flow across IP networks, including
NetBIOS information (for Windows networking) encapsulated within IP or IPX
packets. Therefore, all resources and applications on the remote LAN become
available to the local site.
User sessions through tunnels may specify DES encryption to assure privacy. The use
of the various levels of encryption within a AcerRouter 700 is subject to export
control regulations.
A Configuration Example
Figure 1-7 Connecting Two Private Networks with Internet Access
In Figure 1-7, two AcerRouter 700s are installed in two different locations. Both of
them are connected to the Internet, allowing users to surf the Web. They are also
connected to each other through the ISDN network, forming a private company
company network.
This example also illustrates an important feature of the AcerRouter 700 that both
public and private devices can physically reside on the same LAN.
All devices on both LANs (except for the Web servers) are configured to obtain their
IP addresses automatically (i.e., from the built-in DHCP server in the AcerRouter
700). Since these IP addresses are only used in the local LAN environment, these
devices naturally form a private network (with default IP network address of
192.168.168.0) and are not accessible by users across the Internet. On the other hand,
