Introduction

Content Gateway allows administrators to establish secure communication between the proxy and other computers on the network. Administrators can:

• Control which clients are allowed to access the proxy. See Controlling client access to the proxy.
• Control access to the Content Gateway manager using:
  • Administrator accounts (see Setting the administrator ID and password and Creating a list of user accounts).
  • SSL (Secure Sockets Layer) protection for encrypted, authenticated access (see Using SSL for secure administration).
• Create filtering rules to control access to the Internet, specify special authentication requirements, and control other traffic transiting the proxy. See Content Gateway filtering rules.
• Configure Content Gateway integration into your firewall and control traffic through one or more SOCKS servers. See Configuring SOCKS firewall integration.
• Configure Content Gateway to use multiple DNS servers to match your site’s security configuration. See Using the Split DNS option.
• Configure Content Gateway to perform user authentication. The proxy supports Integrated Windows Authentication (with Kerberos), legacy NTLM (NTLMSSP), LDAP, and RADIUS user authentication. There is also support for multiple authentication methods with multiple authentication realms. See Content Gateway user authentication.
