  • VPN tunnel establishes and passes traffic.
  • VPN tunnel stays up but stops passing traffic
  • believe the tunnel stops passing traffic when lifetimes are reached; won't rekey
  • we moved from ikev2 to ikev1 and had some better results however the tunnel stops passing traffic
  • we upgrade the on-premise ASA to v9.8.4.46 and did not help

really just looking for Azure troubleshooting guidance
