Chapter29 Managing Remote Access VPNs: The Basics

Understanding Remote Access VPNs

Packages are available for the following workstation operating systems (OS). For specific information

on which OS versions that each client supports, see the documentation for the AnyConnect client on

Cisco.com.

•Linux—Packages start with anyconnect-linux, or anyconnect-linux-64 for 64-bit versions.

•Mac OS—Packages start with anyconnect-macosx for Mac OS X on i386 workstations, and

anyconnect-macosx-powerpc for Mac OS X on Power PC workstations.

•Windows—Packages start with anyconnect-win.

You can also download other AnyConnect client packages to the Security Manager server or your local

Security Manager client and use them in remote access policies. However, Security Manager might not

be able to configure newer parameters for those clients, although it might be possible to use FlexConfigs

to configure newer parameters.

For more information on the AnyConnect client, its profiles, and how to configure policies to load the

client onto the device, see the following topics:

Prerequisites for Configuring SSL VPNs

For a remote user to securely access resources on a private network behind an SSL VPN gateway, the

following prerequisites must be met:

•A user account (login name and password).

•An SSL-enabled browser (such as Internet Explorer, Netscape, Mozilla, or Firefox).

•An email client (such as Eudora, Microsoft Outlook, or Netscape Mail).

•One of the following operating systems:

–

Microsoft Windows 2000 or Windows XP, with either JRE for Windows version 1.4 or later, or

a browser that supports ActiveX controls.

–

Linux with JRE for Linux version 1.4 or later. To access Microsoft shared files from Linux in

clientless remote access mode, Samba must also be installed.
