Configuring traversal client zones
The following options are available (in addition to the
common
zone options
) when configuring a traversal client zone on the VCS.
Traversal client zones are used to enable a connection from the
local VCS to a traversal server.
For full details on how traversal client zones and traversal
server zones work together to achieve firewall traversal,
see
Firewall traversal
.
An
NTP server
must also be configured in order for
traversal zones to work.
Authentication username
Traversal clients must always authenticate with traversal servers
by providing their authentication credentials.
This field displays the authentication username that has been
configured on this VCS, which will be used when it is a client
authenticating with a traversal server.
The client authentication username and password are system-
wide settings that are used for all traversal client zones
configured on this VCS. The authentication username cannot be
edited directly from this page but it is shown here for reference
as it is needed when configuring the corresponding traversal
server zone.
To edit the client authentication username, either:
click on the
•
Edit Authentication Username/Password
link.
go to
•
VCS configuration > Authentication > Configuration
.
This will take you to the
Authentication
page, where you can edit
the settings under the
External registration credentials
section.
Protocol
SIP mode
Determines whether SIP calls will be allowed to and from the
traversal server.
SIP port
Specifies the port on the traversal server to be used for SIP calls
to and from the VCS.
SIP transport
Determines which transport type will be used for SIP calls to and
from the traversal server.
For firewall traversal to work via SIP, the traversal server
must have a traversal server zone configured on it to
represent this VCS, using this same transport type and
port number.
H.323 mode
Determines whether H.323 calls will be allowed to and from the
traversal server.
H.323 protocol
Determines which of the two firewall traversal protocols (Assent
or H.460.18) to use for calls to the traversal server. (See
Firewall
traversal protocols
for more information.)
H.323 port
Specifies the port on the traversal server to be used for H.323
calls to and from the local VCS.
For firewall traversal to work via H.323, the traversal
server must have a traversal server zone configured on it
to represent this VCS, using this same port number.
Advanced
!
The Advanced settings should not be changed except on
the advice of TANDBERG customer support.
SIP poison mode
On
: SIP requests sent out this zone will be 'poisoned' such that if
they are received by this VCS again they will be rejected.
Off
: SIP requests sent out to this zone that are received by this
VCS again will not be rejected; they will be processed as normal.
Client settings
Retry interval
Specifies the interval in seconds with which a failed attempt to
establish a connection to the traversal server should be retried.
Location
Peer 1 to Peer 6 address
The IP address or FQDN of the traversal server.
If the traversal server is a VCS Expressway cluster, this should
include all of its peers. See the section
Neighboring the local
VCS to another VCS cluster
for more information.
If the traversal server is a TANDBERG Border Controller, this
should include all its Alternates.
