| RemoteAddr |
| This object specifies together with ipNatPrRemoteMask the the set of IP addresses of remote hosts initiating a session. The table entry will be valid for an incoming packet, when the IP adress of the remote host initiating the session lies in the range specified by both objects. If both objects are set to 0.0.0.0, the table entry will be valid for any remote host. |
| RemoteMask |
| This object specifies together with ipNatPrRemoteAddr the set of IP addresses of remote hosts initiating the session. The table entry will be valid for an incoming packet, when the IP adress of the remote host initiating the session lies in the range specified by both objects. If both objects are set to 0.0.0.0, the table entry will be valid for any remote host. |
| ExtAddr |
| This object specifies together with ipNatPrExtMask the set of destination IP addresses, for which the table entry shall be valid. The entry is valid, if the target IP address of an incoming IP packet lies in the range specified by both objects. If both objects are set to 0.0.0.0, the table entry will be valid for any IP address. |
| ExtMask |
| This object specifies together with ipNatPrExtAddr the set of destination IP addresses, for which the table entry shall be valid. The entry is valid, if the target IP address of an incoming packet lies in the range specified by both objects. If both objects are set to 0.0.0.0, the table entry will be valid for any IP address. |
| ExtPort |
| This object specifies together with ipNatPrExtPortRange the range of port numbers for incoming packets, for which the table entry shall be valid. If both objects are set to -1, the entry is valid for all portnumbers. If ipNatPrPortRange is set to -1, the entry is only valid, when the destination port of an incoming IP packet is equal to ipNatPrExtPort. Otherwise, the entry is valid, if the destination port number lies in the range ExtPort .. ExtPortRange. Range: -1 to 65535 |
| ExtPortRange |
| This object specifies together with ipNatPrExtPort the range of portnumbers for incoming packets, for which the table entry shall be valid. If both objects are set to -1, the entry is valid for all portnumbers. If ipNatPrPortRange is set to -1, the entry is only valid, when the destination portnumber of an incoming IP packet is equal to ipNatPrExtPort. Otherwise, the entry is valid, if the portnumber lies in the range ExtPort .. ExtPortRange. Range: -1 to 65535 |
| IntAddr |
| With ipNatPrIntMask, this object specifies the internal target host's IP address for incoming packets matching the table entry. An incoming packet matching this entry will be routed to the internal server specified by this object and ipNatPrIntMask. If this object is set to 0.0.0.0, the target host will be the original target host in the incoming packet. No translation of the IP-addresses takes place in this case. If ipNatPrIntMask is set to 255.255.255.255, the internal server IP address is ipNatPrIntAddr. If ipNatPrIntMask is a subnet mask, the internal server IP address is the incoming one in which the NET part is mapped according to 'ipNatPrIntAddr / ipNatPrIntMask'. |
| IntPort |
| This object specifies the internal target host's port-number for incoming packets matching the table entry. If this object is set to -1, the target portnumber will be taken from the original incoming packet. No translation of the portnumber will take place in this case. If the set of portnumbers for this table entry is a range instead of a single portnumber, this object will specify the base of the target range of portnumbers. The internal portnumber will be constructed as follows: new-target-port := old-target-port - ipNatPrExtPort + ipNatPrIntPort Range: -1 to 65535 |
| IntMask |
| With ipNatPrIntAddr, this object specifies the internal target host's IP address for incoming packets matching the table entry. An incoming packet matching this entry will be routed to the internal server specified by this object and ipNatPrIntMask. If this object is set to 255.255.255.255, the internal server IP address is ipNatPrIntAddr. If this object is a subnet mask, the internal server IP address is the incoming one in which the NET part is mapped according to 'ipNatPrIntAddr / ipNatPrIntMask'. |
| 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 |
| Descr |
| A textual string describing this NAT forwarding rule. Length: 0 to 255 |
