Step 3
Configure connection profiles, policies, crypto maps, and so on, just as would with single context VPN
configuration of site-to-site VPN.
Configuring Interfaces
An ASA has at least two interfaces, referred to here as outside and inside. Typically, the outside interface
is connected to the public Internet, while the inside interface is connected to a private network and is
protected from public access.
To begin, configure and enable two interfaces on the ASA. Then, assign a name, IP address and subnet
mask. Optionally, configure its security level, speed, and duplex operation on the security appliance.
Note
The ASA’s outside interface address (for both IPv4/IPv6) cannot overlap with the private side
address space.
To configure interfaces, perform the following steps, using the command syntax in the examples:
Step 1
To enter Interface configuration mode, in global configuration mode enter the
interface
command with
the default name of the interface to configure. In the following example the interface is ethernet0.
hostname(config)#
interface ethernet0/0
hostname(config
-
if)#
Step 2
To set the IP address and subnet mask for the interface, enter the
ip address
command. In the following
example the IP address is 10.10.4.100 and the subnet mask is 255.255.0.0.
hostname(config-if)#
ip address 10.10.4.100 255.255.0.0
hostname(config-if)#
Step 3
To name the interface, enter the
nameif
command, maximum of 48 characters. You cannot change this
name after you set it. In the following example the name of the ethernet0 interface is outside.
hostname(config-if)#
nameif outside
hostname(config-if)#
#
Step 4
To enable the interface, enter the
no
version of the
shutdown
command. By default, interfaces are
disabled.
hostname(config-if)#
no shutdown
hostname(config-if)#
Step 5
To save your changes, enter the
write memory
command:
hostname(config-if)#
write memory
hostname(config-if)#
Step 6
To configure a second interface, use the same procedure.
