Configuring an ANG-3000/7000
Figure 12 shows a sample corporate network that employs two virtual
subnets. Each virtual subnet provides up to 255 client IP addresses depending
upon the subnet mask used. By assigning different virtual subnets to each
group, you can control what devices members of the group can access once
they are connected.
Figure 12 Remote Client Virtual Subnet Usage
For example, because Server #1 resides on the same network segment as the
ANG, all remote clients can access this server regardless of the virtual subnet
that provided their address. If you enable RIP or OSPF on the ANG Trusted
interface, the router in this diagram will learn about both virtual subnets.
However, if you enable only static routing on the ANG Trusted interface, you
can limit access to the 200.100.201.0 subnet to users that receive address from
Virtual Subnet #1. To accomplish this, you must create two static routes:
Firewall
Virtual Subnet #1
192.168.1.0
Virtual Subnet #2
192.168.2.0
INTERNET
Server #1
Router
Server #2
200.100.200.0
200.100.201.0
