Transparent Mode Running Site to Site VPN on Bridge0 IP Interface

[ntkevinshao]

I am trying to configure an OpnSense(in Transparent Bridge Mode) to run IPsec site to site VPN, but failed 
Bridge0 member : LAN, WAN
LAN, WAN IP address : none
Bridge0 is assigned an IP address for management and hopefully for site to site VPN
Can we config IPsec Site to Site VPN using Bridge0 IP interface ?
My lab config is as below :
Remote OpnSense(Site to Site VPN Peer)  --- External Firewall at local site with Port Forwarding enabled for IPsec --- Local OpnSense in Transparent Mode configured for IPsec Site to Site VPN
I hope the 192.168.66.0 /24 remote subnet can reach local 192.168.0.0 /22 subnet each other, but failed.
Is this due to Bridge0 limitation ?
