Description: Port mapping behavior is the policy governing the selection of external address and port in a given realm for a given five-tuple of source address and port, destination address and port, and protocol.
endpointIndependent(0), the behavior REQUIRED by RFC 4787, REQ-1, maps the source address and port to the same external address and port for all destination address and port combinations reached through the same external realm and using the given protocol.
addressDependent(1) maps to the same external address and port for all destination ports at the same destination address reached through the same external realm and using the given protocol.
addressAndPortDependent(2) maps to a separate external address and port combination for each different destination address and port combination reached through the same external realm.
What is natv2InstancePortMappingBehavior?
Reports the NAT instance's port-mapping policy, endpoint-independent, address-dependent, or address-and-port-dependent, which determines whether the same internal endpoint gets the same external address/port for every destination or a different one per destination; an admin checks this when troubleshooting why certain peer-to-peer or gaming applications behave inconsistently through this NAT.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.234.2.1.1.3 snmpwalk -v2c -c public <target> NATV2-MIB::natv2InstancePortMappingBehavior
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.234.2.1.1.3.1 snmpget -v2c -c public <target> NATV2-MIB::natv2InstancePortMappingBehavior.1
