Chapter 4 Using the Command-Line Interface for Quick Configuration
Configuring the Public Interface
Step 3
The system prompts for a subnet mask.
> Enter Subnet Mask
Quick Public Interface -> [ 255.0.0.0 ]
Enter the subnet mask for this interface, using dotted decimal notation. The default is a standard subnet
mask appropriate for the IP address you just entered. For example, an IP address of 192.168.12.34 is a
Class C address, and the standard subnet mask is 255.255.255.0. You can accept this entry or change it.
Step 4
When you press Enter, the system prompts you to specify a default gateway, which is the system to which
the VPN 3002 should forward packets. In other words, if the VPN 3002 has no configured static routes
that specify where to send packets, it sends them to this gateway. (When you first start the VPN 3002, it
has no static routes.)
> Default Gateway
Quick -> _
At the cursor, enter the IP address of the default gateway (for example,
10.10.0.1
). This address must
not be the same as the IP address configured on any VPN 3002 interface. To specify no default gateway,
which means the VPN 3002 drops unrouted packets, leave this entry blank. If you are using DHCP to
acquire the public IP address, DHCP usually supplies the default gateway, and you should leave this field
blank.
The system proceeds to the IPSec parameters; see the section,”
Configuring IPSec
.”
