Description: Manages AT&T VPN gateway devices, providing tunnel establishment status, authentication events, and throughput metrics.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ATT-VPN-GATEWAY-MIB?

ATT-VPN-GATEWAY-MIB is AT&T's enterprise MIB for its managed VPN Gateway customer-premises equipment, used to remotely manage and monitor small-business/branch VPN gateway devices as part of an AT&T managed-service offering. It exposes hardware and firmware identity (hardware version, code/firmware version), account and time-zone/DST configuration, WAN connection method and hostname, and a DNS server table, alongside tunnel/authentication and throughput data per the module's broader scope. It supports monitoring both software status - code/firmware version, DST/timezone configuration, WAN connection method - and basic device hardware version identity, which AT&T's back-end systems use to verify the gateway is running expected firmware and is correctly provisioned. It is a self-contained enterprise MIB but is used alongside standard host/interface MIBs by the managed-service monitoring platform for full device visibility. It is typically deployed on AT&T-managed VPN gateway appliances installed at customer branch/small-business sites and polled by AT&T's remote management infrastructure, with technicians performing an ATT-VPN-GATEWAY-MIB download to load the module into their SNMP management platform.

IPNetwork Monitor allows you to monitor SNMP objects defined in ATT-VPN-GATEWAY-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • AT&T managed VPN gateway (branch/small-business CPE)

Monitoring Examples

A management system would poll nghwHardwareVersion and nghwCodeVersion to confirm the gateway is on approved hardware/firmware, and check nghwWanConnectionMethod and nghwHostname to verify WAN provisioning. Walking ngDnsTable/ngDnsEntry via ngdnIndex reveals which DNS servers are configured on the gateway. A mismatch between nghwCodeVersion and the expected fleet-wide firmware version would flag a device needing a firmware upgrade, while an unexpected nghwDstActive value could explain time-stamping discrepancies in logs.

What Can Be Monitored

  • hardware version
  • firmware/code version
  • WAN connection method
  • DNS server configuration
  • DST/timezone status
  • account identity
