natAddrPortBindGlobalPort

Module: NAT-MIB

OID (symbolic): NAT-MIB::natAddrPortBindGlobalPort

OID (numeric): 1.3.6.1.2.1.123.1.8.1.7

Node type: OBJECT-TYPE

Type: InetPortNumber

Access: read-only

Description: For a protocol value TCP or UDP, this object represents the public-realm-specific port number. On the other hand, for ICMP a bind is created only for query/response- type ICMP messages such as ICMP echo, Timestamp, and Information request messages, and this object represents the public-realm-specific identifier in the ICMP message, as defined in RFC 792 for ICMPv4 and in RFC 4443 for ICMPv6.

This object, together with natAddrPortBindProtocol, natAddrPortBindGlobalAddrType, and natAddrPortBindGlobalAddr, constitutes a session endpoint in the public realm. A bind entry binds a public-realm-specific endpoint to a private-realm- specific endpoint, as represented by the tuple of (natAddrPortBindLocalPort, natAddrPortBindProtocol, natAddrPortBindLocalAddrType, and natAddrPortBindLocalAddr). Deprecated in favor of NATV2-MIB.

What is natAddrPortBindGlobalPort?

For TCP/UDP, the public-side port number this NAPT binding uses; for ICMP, the public-side identifier from an echo/timestamp/info-request message. Combined with the global address and protocol, this is the externally-visible half of a port-translated connection. Deprecated in favor of NATV2-MIB.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.123.1.8.1.7
snmpwalk -v2c -c public <target> NAT-MIB::natAddrPortBindGlobalPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.123.1.8.1.7.1
snmpget -v2c -c public <target> NAT-MIB::natAddrPortBindGlobalPort.1
