You must add the appropriate ingress and egress rules to allow ping traffic. Note that the VCN's default security list does not allow ping traffic (ICMP type 8 and ICMP type 0). VCN security lists: Ensure you've set up the VCN security lists to allow the desired traffic (both ingress and egress rules).For more details about the appropriate configuration, contact your CPE vendor's Your CPE is configured to handle traffic coming from your VCN on any of the tunnels.ДЇor example, you need to disable ICMP inspection, configure TCP state bypass, and so Multiple Tunnels If you have multiple tunnels up simultaneously, ensure that With policy-based configuration, you can configure only a single tunnel between yourД¬isco ASA and your dynamic routing gateway (DRG).

Local IKE identifier: Some CPE platforms do not allow you to change the local If you want one IPSec connection as primary and another one as backup, configure more-specific routes for the primary connection and less-specific routes (or the default route of 0.0.0.0/0) on the backup connection. If both IPSec connections have only a default route (0.0.0.0/0) configured, traffic will route to either of those connections because Oracle uses asymmetric routing. Multiple IPSEC Connections: You can use two IPSec connections for redundancy. 'IP SLA Configuration' in the Cisco ASA policy-based configuration template.
