HTTP meta tags 
for cache control 
(recommended)

Select this checkbox to apply HTTP meta tag cache control directives to this portal 
layout. Cache control directives include:
<meta http-equiv=”pragma” content=”no-cache”> 

<meta http-equiv=”cache-control” content=”no-cache”>

<meta http-equiv=”cache-control” content=”must-revalidate”>
Note: NETGEAR strongly recommends enabling HTTP meta tags for security reasons 
and to prevent out-of-date Web pages, themes, and data being stored in a user’s Web 
browser cache.

ActiveX web 
cache cleaner

Select this checkbox to enable ActiveX cache control to be loaded when users log in to 
the SSL VPN portal. The Web cache cleaner prompts the user to delete all temporary 
Internet files, cookies, and browser history when the user logs out or closes the Web 
browser window. The ActiveX Web cache control is ignored by Web browsers that do 
not support ActiveX.

VPN Tunnel page Select this checkbox to provide full network connectivity.

Port Forwarding

Select this checkbox to provides access to specific defined network services.
Note: Any pages that are not selected are not visible from the SSL VPN portal; 
however, users can still access the hidden pages unless you create SSL VPN access 
policies to prevent access to these pages.
