What Should I Pay Attention to When Configuring IPSec VPN in Hot Standby Networking?
Solution
• The service interfaces (including VLANIFs) connecting the firewall to upstream and downstream devices must work at Layer 3.

• Before configuring IPSec VPN, you must establish the hot standby status. The IPSec policy configured on the active firewall will be automatically synchronized to the standby one. On the standby firewall, you only need to apply the synchronized IPSec policy to the outgoing interface.

• If the firewall serves as the initiator of the IPSec tunnel, you must run the local-address ip-address command to specify the virtual IP address of the VRRP group as the IP address for IPSec negotiation.

• Configure DPD to delete the tunnel that has been established on the original active firewall after an active/standby switchover to prevent packet loss.
