>> Table: ipNatOutTable - (.1.3.6.1.4.1.272.4.5.18.1)

Description: This table specifies the IP address translation for outgoing sessions. If no matching entry is found the IP address is set to the IP address defined on the interface configured for NAT. If a matching entry is found, the source IP address of outgoing IP packets is translated according to the couple 'ipNatOutExtAddr / ipNatOutExtMask'.

- If external IP address is a 'host IP address', the whole source IP address is mapped. - If external IP address is a 'net IP address', only the 'net part' of source IP address is affected. This table is only used if the outgoing address translation is activated (ipExtIfNatOutXlat).

Entries in the table are created and removed manually by network management.

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)
  • ggp (3)
  • ip (4)
  • tcp (6)
  • egp (8)
  • igp (9)
  • pup (12)
  • chaos (16)
  • udp (17)
  • hmp (20)
  • xns-idp (22)
  • rdp (27)
  • ipv6 (41)
  • rsvp (46)
  • gre (47)
  • esp (50)
  • ah (51)
  • tlsp (56)
  • skip (57)
  • kryptolan (65)
  • iso-ip (80)
  • igrp (88)
  • ospf (89)
  • ipip (94)
  • ipx-in-ip (111)
  • vrrp (112)
  • 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.

Range: -1 to 65535

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.

Range: -1 to 65535

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.

Range: -1 to 65535

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.

Range: -1 to 65535

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.

Range: 0 to 5184000
