Transparent Mode Access

20Introducing the VPN Gateway

Access to intranet resources in transparent mode, that is, without going through the Web Portal, is accomplished using Windows VPN clients installed on the client PCs. In this mode, remote users will experience network access as if sitting within the local area network. The following VPN clients are available:

•Nortel SSL VPN client (TDI and LSP version).

•Nortel IPsec VPN client (formerly the Contivity VPN client). Not supported on the ASA 310, ASA 310-FIPS and ASA 410 hardware models.

•Net Direct installable client.

User Authentication

User authentication is supported using the following methods:

•RADIUS (including Challenge/Response)

•LDAP (including Microsoft Active Directory)

•NTLM (Windows NT Domain, including Microsoft Active Directory)

•Secure Computing SafeWord (RADIUS)

•Netegrity SiteMinder

•RSA SecurID (native or through RADIUS)

•RSA ClearTrust

•ActivCard (RADIUS)

•Novell NDS/eDirectory (LDAP)

•Client certificate authentication

•Local database authentication

User Authorization

User authorization is controlled through the user’s group membership. Two different authorization profile types are supported:

•The base profile defines a group member’s access rights to networks, services and paths.

•The extended profile (optional) also defines a group member’s access rights depending on conditions related to the user’s connection, for example, source network, authentication method, access method, client certificate installed and/or Tunnel Guard checks passed.
