How to configure Cisco ASA 5540 with Cisco AnyConnect VPN client?
Open the “Cisco Anyconnect VPN Client” software (it must be installed on your PC after connecting for the first time on the ASA) and click on “Preferences” button (it is next to “Connect to: IP address”). Then click on “Enable Local LAN Access“. Azamsays December 1, 2012 at 8:47 am Please check the following which I configured on ASA 5540 8.4(2)
What VPNs are supported by Cisco ASA 5500 firewalls?
That is, the Web SSL VPN does not provide full network visibility to the remote user. The user has access only to specific applications (like internal email, internal files etc). Both IPSec VPNs and SSL VPNs are supported by Cisco ASA 5500 firewalls. The newest generation of remote access VPNs is offered from Cisco AnyConnect SSL VPN client.
How to access ASA from inside interface of VPN?
You should enable ssh or asdm to allow access from the IP pool which is assigned to the VPN users. Then you can access the ASA on the inside interface. Stevesays

What is ASA 5505?
If you have an ASA 5505 security appliance (version 7.2 (3) or higher) configured as an Easy VPN Client in Network Extension Mode with multiple interfaces configured, the security appliance builds a tunnel for locally encrypted traffic only from the interface with the highest security level .
Which interface has the highest security level?
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.
Can Cisco ASA 5505 be used as a VPN?
When configuring the Cisco ASA 5505 as an Easy VPN hardware client, you can specify a tunnel group or trustpoint configured on the Easy VPN server, depending on the Easy VPN server configuration. See the section that names the option you want to use:
Can Cisco devices be used for authentication?
Devices such as Cisco IP phones, wireless access points, and printers are incapable of performing authentication . Enter the following command in global configuration mode to exempt such devices from authentication, thereby providing network access to them, if individual user authentication is enabled:
What is Cisco ASA 5505?
The Cisco ASA 5505, operating as an Easy VPN hardware client, supports management access using SSH or HTTPS, with or without a second layer of additional encryption. You can configure the Cisco ASA 5505 to require IPsec encryption within the SSH or HTTPS encryption.
Which interface has the highest security level?
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.
Can Cisco ASA 5505 be used as a VPN?
When configuring the Cisco ASA 5505 as an Easy VPN hardware client, you can specify a tunnel group or trustpoint configured on the Easy VPN server, depending on the Easy VPN server configuration. See the section that names the option you want to use:
Does Easy VPN use UDP?
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.
Can Cisco devices be used for authentication?
Devices such as Cisco IP phones, wireless access points, and printers are incapable of performing authentication . Enter the following command in global configuration mode to exempt such devices from authentication, thereby providing network access to them, if individual user authentication is enabled:
What is ASA 5505?
A very popular scenario for small networks is to have a Cisco ASA 5505 as border firewall connecting the LAN to the Internet. Administrators in such networks are usually encountered with requests from their users that are not very security conscious.
Can a remote desktop be attacked by a password?
Remote Desktop machines are very prone to attacks, especially brute- force password attacks. In windows, the administrator account does not get locked-out by default. So a brute force administrator password attack on the RDP server from remote attackers can be successful especially if the administrator password is weak.
Is the IP address of an ASA fixed?
Assume that the ASA receives IP address dynamically from the ISP (via DHCP protocol). So the outside IP of the ASA is not fixed.
Can you create 3 DMZ vlans?
However, companies with limited budget might have purchased a Cisco ASA 5505 with basic license which restricts the creation of a DMZ Vlan (although you can create 3 Vlans, the third Vlan can only communicate with one of the other two Vlans but not both).
ASA Easy VPN (EZVPN) Configuration
The configuration of the Easy VPN server side is very similar to a "typical" remote access server configuration using group policy. Table 1 reviews the steps that are required to perform this configuration.
Summary
The configuration of a VPN can be daunting, and getting it to work as expected can be very challenging. Cisco's Easy VPN feature allows at least the client configuration to be as easy as possible and enables the relatively small ASA 5505 to become a well-secured, easily configured hardware client.
What version of Cisco AnyConnect is supported?
The Cisco AnyConnect VPN is supported on the new ASA 8.x software and later version and provides remote access to users with just a secure Web Browser (https).
What IP address does AnyConnect use?
The remote users, after successful authentication, will receive an IP address from local ASA pool 192.168.100.1-50. The internal ASA network will use subnet range 192.168.5.0/24
How to get AnyConnect client software?
The first step is to obtain the AnyConnect client software from the Cisco Software Download Website. You will need to download the appropriate software version according to the Operating System that your users have on their computers.
What happens when SSL is stopped?
When the SSL connection is stopped, the SSL client either uninstalls itself or remains on the user’s PC (depending on the configuration of the ASA).
What does a remote teleworker open?
For first time user connection, the remote teleworker just opens a browser pointing to https://<ASA-outside-public-IP>.
What is the address of a remote host?
Address or name of remote host ? 192.168.5.10
Is Cisco ASA Firewall Fundamentals self published?
He is a self-published author of two books ("Cisco ASA Firewall Fundamentals" and "Cisco VPN Configuration Guide") which are available on Amazon and on this website as well.
