Chapter 1 Configuring Easy VPN Services on the ASA 5505
Configuring Automatic Xauth Authentication
In this scenario, the security appliance builds the tunnel only for vlan1, the interface with the highest
security level. If you want to encrypt traffic from vlan12, you must change the security level of interface
vlan1 to a lower value than that of vlan 12.
Configuring Automatic Xauth Authentication
The ASA 5505 configured as an Easy VPN hardware client automatically authenticates when it connects
to the Easy VPN server if all of the following conditions are true:
•
Secure unit authentication is disabled on the server.
•
The server requests IKE Extended Authenticate (Xauth) credentials.
Xauth provides the capability of authenticating a user within IKE using or RADIUS.
Xauth authenticates a user (in this case, the Easy VPN hardware client) using RADIUS or any of the
other supported user authentication protocols.
•
The client configuration contains an Xauth username and password.
Enter the following command in global configuration mode to configure the Xauth username and
password:
vpnclient username
xauth_username
password
xauth password
You can use up to 64 characters for each.
For example, enter the following command to configure the Easy VPN hardware client to use the
XAUTH username testuser and password ppurkm1:
hostname(config)#
vpnclient username testuser password ppurkm1
hostname(config)#
To remove the username and password from the running configuration, enter the following command:
no vpnclient username
For example:
hostname(config)#
no vpnclient username
hostname(config)#
Configuring IPsec Over TCP
By default, the Easy VPN hardware client and server encapsulate IPsec in User Datagram Protocol
(UDP) packets. Some environments, such as those with certain firewall rules, or NAT and PAT devices,
prohibit UDP. To use standard Encapsulating Security Protocol (ESP, Protocol 50) or Internet Key
Exchange (IKE, UDP 500) in such environments, you must configure the client and the server to
encapsulate IPsec within TCP packets to enable secure tunneling. If your environment allows UDP,
however, configuring IPsec over TCP adds unnecessary overhead.
To configure the Easy VPN hardware client to use TCP-encapsulated IPsec, enter the following
command in global configuration mode:
vpnclient ipsec-over-tcp
[
port
tcp_port
]
The Easy VPN hardware client uses port 10000 if the command does not specify a port number.
