Table 13-7: NAT Translation Table Parameter Descriptions
Parameter Description
Source
'Index'
index
[NATTranslation_
Index]
Defines an index number for the new table row.
Note: Each row must be configured with a unique index.
'Source Interface'
src-interface-
name
[NATTranslation_
SrcIPInterfaceName]
Assigns an IP network interface (configured in the IP Interfaces table)
to the rule. Outgoing packets sent from the specified network
interface are NAT'ed.
By default, no value is defined.
To configure IP network interfaces, see Configuring IP Network
Interfaces.
'Source Start Port'
src-start-port
[NATTranslation_
SourceStartPort]
Defines the optional starting port range (0-65535) of the IP interface,
used as matching criteria for the NAT rule. If not configured, the
match is done on the entire port range. Only IP addresses and ports of
matched source ports will be replaced.
'Source End Port'
src-end-port
[NATTranslation_
SourceEndPort]
Defines the optional ending port range (0-65535) of the IP interface,
used as matching criteria for the NAT rule. If not configured, the
match is done on the entire port range. Only IP addresses and ports of
matched source ports will be replaced.
Target
'Target IP Address'
target-ip-
address
[NATTranslation_
TargetIPAddress]
Defines the global (public) IP address. The device adds the address
in the outgoing packet to the SIP Via header, Contact header, 'o='
SDP field, and 'c=' SDP field.
'Target Start Port'
target-start-
port
[NATTranslation_
TargetStartPort]
Defines the optional starting port range (0-65535) of the global
address. If not configured, the ports are not replaced. Matching
source ports are replaced with the target ports. This address is set in
the SIP Via and Contact headers and in the 'o=' and 'c=' SDP fields.
'Target End Port'
target-end-port
[NATTranslation_
TargetEndPort]
Defines the optional ending port range (0-65535) of the global
address. If not configured, the ports are not replaced. Matching
source ports are replaced with the target ports. This address is set in
the SIP Via and Contact headers and in the 'o=' and 'c=' SDP fields.

packets to a remote UA that is located behind NAT.
