Glossary

HTTP Proxy

Applies to the SSL VPN feature. Java applet accessible on the
Portal page’s Advanced tab, enabling links executed on complex
intranet Web pages (containing plugins like Flash, Shockwave and
Java applets) to be sent through a secure connection to the SSL
server for redirection.

IP Interface

IP interfaces are defined on the Nortel Application Switch and
are used for defining the subnets to which the switch belongs.
Up to 256 IP interfaces can be configured on a Nortel Application
Switch. The IP address assigned to each IP interface provides the
switch with an IP presence on your network. No two IP interfaces
can be on the same IP subnet. The IP interfaces can be used for
connecting to the switch for remote configuration, and for routing
between subnets and VLANs (if used).

Master

A VPN Gateway in a cluster that is in control of the MIP address,
or can take over the control of the MIP address should another
master fail. Configuration changes in the cluster are propagated to
other members through the master VPN Gateways.

MIB (Management Information Base)

An SNMP structure that describes which groups and objects can
be monitored on a particular device.

MIP (Management IP) Address

An IP address that is an IP alias to a master VPN Gateway in a
cluster of VPN Gateways. The MIP address identifies the cluster
and is used when making configuration changes through a Telnet
or SSH connection or through the Browser-Based Management
Interface (BBI).

Net Direct Client

The Net Direct client is an SSL VPN client that can be
downloaded from the Portal for each user session. As opposed to
the LSP and TDI versions of the SSL VPN client, the Net Direct
client does not have a user interface. Another difference is that
the Net Direct client is packet-based, while the SSL VPN clients
uses system calls. The packet-based solution supports more
applications (e.g. Microsoft Outlook).
