Once in interface configuration mode, you can assign physical interfaces to switchports and enable them turn them on or you can assign names and security levels to VLAN interfaces. The nameif command gives the interface a name and assigns a security level. Typical names are outside, inside, or DMZ.
Security levels are numeric values, ranging from 0 to , used by the appliance to control traffic flow. Traffic is permitted to flow from interfaces with higher security levels to interfaces with lower security levels, but not the other way. Access-lists must be used to permit traffic to flow from lower security levels to higher security levels. The default security level for an outside interface is 0.
For an inside interface, the default security level is In the following sample configuration, the interface command is first used to name the inside and outside VLAN interfaces, then the DMZ interface is named and a security level of 50 is assigned to it. With modern versions of security appliance software, it is not necessary to explicitly configure default subnet masks. If you are using non-standard masks, you must explicitly configure the mask, otherwise, it is not necessary.

In the next example, the interface command is used to identify physical interfaces, assign them to switchports on the appliance, and enable them turn them on. This command is not used on the ASA 55x0 appliances. The network option states that this particular object will be based on IP addresses.
The Complete Cisco VPN Configuration Guide
The subnet 0. After you select and download your client software, you can tftp it to your ASA. After the file has been uploaded to the ASA, configure this file to be used for webvpn sessions.
Note that if you have more than one client, configure the most commonly used client to have the highest priority. In this case, we're using only one client and giving it a priority of 1. Group Policies are used to specify the parameters that are applied to clients when they connect.
In this case, we'll create a group policy named SSLClient. As remote access clients connect to the ASA, they connect to a connection profile, which is also known as a tunnel group. We'll use this tunnel group to define the specific connection parameters we want them to use. Now we need to tell the ASA not to NAT the traffic between the remote access clients and the internal network they will be accessing.
First we'll create an access list that defines the traffic, and then we'll apply this list to the nat statement for our interface. Now we're ready for some user accounts. Here we'll create a user and assign this user to our remote access vpn. Verify your configuration by establishing a remote access session and use the following show command to view session details.
This guide should help you to get your remote access users up and running in no time.
