Reducing this rekeying time will increase the security characteristics of the IPsec tunnels; however, consideration should be made as to performance impacts for both the FortiGate and the peer eNB/gNB devices. BGP and IPSEC have their timers which can be adjusted to make failover and recovery of links quicker. Solution: If no value is set for 'keepalive-failtimes', FortiGate will use '10' which is the default value: With the keepalive properly configured and matching on local and remote ends, run 'diagnose sys gre keepalive' to monitor it: This causes the peer to think it is behind a NAT device, and it will use UDP encapsulation for IPsec, even if no NAT is present.
