IfIndex
This object specifies the interface index, for which the

table entry shall be valid. If set to 0, the entry will

be valid for all interfaces configured to use NAT.
Protocol
This object specifies the protocol, for which the table

entry shall be valid.
Enumerations:
  • icmp (1)
  • tcp (6)
  • udp (17)
  • ipv6 (41)
  • gre (47)
  • esp (50)
  • ah (51)
  • l2tp (115)
  • any (255)
  • delete (256)
RemoteAddr
This object specifies together with ipNatOutRemoteMask the

set of target IP addresses for which the table entry is  

valid. If both objects are set to 0.0.0.0, the table entry

will be valid for any target IP address.
RemoteMask
This object specifies together with ipNatOutRemoteAddr the

set of target IP addresses for which the table entry is  

valid. If both objects are set to 0.0.0.0, the table entry

will be valid for any target IP address.
ExtAddr
With ipNatOutExtMask, this object specifies the external 

'IP address' or 'NET address' to which the internal IP address 

is mapped.

- To map exactly to ipNatOutExtAddr (i.e. map to a single IP 

address), ipNatOutExtMask MUST be set to 255.255.255.255

- To keep HOST part of source IP address and map only the

NET part, ipNatOutExtMask MUST be the related subnet mask

(and it should be the same as ipNatOutIntMask ).
RemotePort
This object specifies together with ipNatOutRemotePortRange

the range of portnumbers for outgoing calls, for which the

table entry shall be valid. If both objects are set to -1, the

entry is valid for all portnumbers. If ipNatOutPortRange

is set to -1, the entry is only valid, when the portnumber 

of an outgoing call is equal to ipNatOutRemotePort.

Otherwise, the entry is valid, if the called portnumber

lies in the range RemotePort .. RemotePortRange.
RemotePortRange
This object specifies together with ipNatOutRemotePort

the range of portnumbers for outgoing calls, for which the

table entry shall be valid. If both objects are set to -1, the

entry is valid for all portnumbers. If ipNatOutPortRange

is set to -1, the entry is only valid, when the portnumber 

of an outgoing call is equal to ipNatOutRemotePort.

Otherwise, the entry is valid, if the called portnumber

lies in the range RemotePort .. RemotePortRange.
IntAddr
This object specifies together with ipNatOutIntMask

the internal hosts IP address for outgoing calls 

matching the table entry. If both objects are set to 

0.0.0.0, the table entry will be valid for any source 

IP address.
IntMask
This object specifies together with ipNatOutIntAddr

the internal hosts IP address for outgoing calls 

matching the table entry. If both objects are set to 

0.0.0.0, the table entry will be valid for any source 

IP address.
IntPort
This object specifies the internal source port for which the

table entry shall be valid. If this object is set to -1, 

any internal source port matches this entry.
ExtPort
This object may be used to specify a fixed external source 

port to which the internal source port is mapped. 

If this object is set to -1, the port is mapped to the next 

free source port available.
ExtMask
With ipNatOutExtAddr, this object specifies the external 

'IP address' or 'NET address' to which the internal IP address 

is mapped.

- To map exactly to ipNatOutExtAddr (i.e. map to a single IP 

address), ipNatOutExtMask MUST be set to 255.255.255.255

- To keep HOST part of source IP address and map only the

NET part, ipNatOutExtMask MUST be the related subnet mask

(and it should be the same as ipNatOutIntMask).
Timeout
When there is no traffic associated with a NAT entry, this 

entry is discarded at the end of a timeout value. This object 

holds this timeout value in seconds. If set to the default 

value of 0, the timeout will be set to the value specified 

either in ipExtIfNatTcpTimeout or ipExtIfNatOtherTimeout, 

depending on the protocol.
