Running into an issue with IPsec: I have a pair of firewalls with HA and a single opnsense firewall, the IPsec tunnel is able to establish on the primary firewall with the WAN1 VIP but when I enter CARP maintenance mode the IPsec tunnel does not establish on the standby firewall when it's active. The only way I can get this to work is utilizing DPD with time of 1 second and action of restart on the stand alone firewall. I do have MOBIKE disabled on the HA pair and the stand alone firewall.
Firewall version: 21.7.1
Any help is appreciated.

Hello All,
I have a slightly different question but in the same area (HA and IPsec VPN)
Could you guys help me with the idea to pick a method to disable IPsec on the standby node?
The only idea I have is to configure FRR and run OSPF with upstream router. After that it will be possible to advertise 0.0.0.0/0 to both active and standby OPNsenses and to disable FRR on standby, so VPN establishment process could be started only from active node with default route.
Kind regards,
Serg GR

Hi,
You just have to attach IPSEC tunnel to VIP interface, so it won't be able to go up if doesn't own the VIP.
