acSysSTUNBindingLifeTime
Module: AC-SYSTEM-MIB
OID (symbolic): AC-SYSTEM-MIB::acSysSTUNBindingLifeTime
OID (numeric): 1.3.6.1.4.1.5003.9.10.10.1.3.6.21.4
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This parameter is used to define the NAT binding lifetime, in seconds. STUN refreshes the binding information after this time expires. Range = 0 - 2592000. Access: Offline. AC INI-Param: NATBINDINGDEFAULTTIMEOUT
What is acSysSTUNBindingLifeTime?
This OID defines the NAT binding lifetime in seconds (0–2,592,000 range, roughly 30 days max), after which STUN refreshes the NAT mapping. An engineer sets this based on the NAT device's timeout—if set too high, the NAT may forget the binding and break the connection. For example, setting it to 300 means the device refreshes its NAT binding every 5 minutes to keep the mapping alive.
