Cisco ASA 5500 Series Configuration Guide using ASDM
Chapter 72 Configuring Clientless SSL VPN
Configuring Browser Access to Plug-ins
Prerequisites
Make sure clientless SSL VPN (“webvpn”) is enabled on an ASA interface.
Restrictions
Do not specify an IP address as the common name (CN) for the SSL certificate. The remote user attempts
to use the FQDN to communicate with the ASA. The remote PC must be able to use DNS or an entry in
the System32\drivers\etc\hosts file to resolve the FQDN.
Go to the section that identifies the type of plug-in you want to provide for clientless SSL VPN access.

Installing Plug-ins Redistributed By Cisco
Cisco redistributes the following open-source, Java-based components to be accessed as plug-ins for web
browsers in clientless SSL VPN sessions.
Prerequisites
• Make sure clientless SSL VPN (“webvpn”) is enabled on an interface on the ASA. To do so, enter
the show running-config command.
• Create a temporary directory named “plugins” on a local TFTP or FTP server (for example, with the
hostname “local_tftp_server”), and download the plug-ins from the Cisco web site to the “plugins”
directory.
