Firewall Traversal and Authentication
Client Type and Client Settings Server Type and Server Settings
VCS
The VCS client provides its Authentication Username and
Authentication Password. These are set on the client via VCS
Configuration > Authentication > Configuration.
•
VCS Border Controller
The traversal server zone for that client must be configured with the
client’s Authentication Username. This is set via VCS Configuration >
Zones > Edit Zone.
There must also an entry in the server’s authentication database
with the corresponding username and password.
•
•
Endpoint Client
The endpoint client provides its Authentication ID and Authentication
Password.
•
VCS Border Controller
There must be an entry in the server’s authentication database with
the corresponding username and password.
•
Gatekeeper Client
The Gatekeeper client looks up its System Name in its own
authentication database and retrieves the password for that name.
It then provides this name and password.
•
VCS Border Controller
The traversal server zone for the Gatekeeper client must
be configured with the Gatekeeper’s System Name
in the Authentication Username field. This is set via
VCS Configuration > Zones > Edit Zone.
There must be an entry in the server’s authentication database with
the corresponding username and password.
•
•
VCS
If Authentication is On on the Border Controller, the VCS client
provides its Authentication Username and Authentication Password.
These are set on the client via VCS Configuration > Authentication >
Configuration.
If the Border Controller is in Assent mode, the VCS client provides
its Authentication Username. This is set on the client via VCS
Configuration > Authentication > Configuration.
•
•
Border Controller
If Authentication is On on the Border Controller, there must be
an entry in the Border Controller’s authentication database
that matches the VCS client’s Authentication Username and
Authentication Password.
If the Border Controller is in Assent mode, the traversal zone
configured on the Border Controller to represent the VCS client must
use the client’s Authentication Username in the Assent Account
name field. This is set on the Border Controller via TraversalZone >
Assent > Account name.

Overview
In order to control usage of the VCS as a
traversal server, each VCS or Gatekeeper that
wishes to be its client must first authenticate
with it.
Upon receiving the initial connection request
from the traversal client, the VCS Border
Controller asks the client to authenticate
itself by providing a username and password.
The server then looks up the username and
password in its own authentication database.
If a match is found, the VCS server will accept
the request from the client.
The settings used for authentication depend
on the combination of client and server
being used. These are detailed in the table
opposite.
When acting as a VCS Border
Controller, authentication is required
from all VCS and Gatekeeper clients
regardless of the VCS’s Authentication Mode
setting. This setting will however still
determine whether or not endpoint clients are
required to authenticate.
