Configuring Traversal Client Zones
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
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.
SIP transport
Determines which transport type will be used
for SIP calls 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.
Retry interval
Specifies the interval in seconds with which a
failed attempt to establish a connection to the
traversal server should be retried.
Primary address
Specifies the IP address or FQDN of the
traversal server.
Alternate 1 to Alternate 5 address
Specifies the IP addresses or FQDNs of any
alternates configured on the traversal server.
H.323 mode
Determines whether H.323 calls will be allowed
to and from the traversal server.
SIP mode
Determines whether SIP calls will be allowed to
and from this zone.
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.
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.
For full details on how traversal client
zones and traversal server zones work
together to achieve firewall traversal,
see
Authentication username
Traversal clients must always authenticate
with traversal servers by providing their
authentication username and password.
The client’s authentication username is
shown here for reference, to make it easier
to configure the corresponding zone on the
traversal server.
The authentication username is a system-wide
setting that is set via
VCS Configuration >
Authentication > Configuration
.
