IPSec VTI pfSense 2.4.4 to pfsense 2.4.4

[bobkoure]

I have tunnels up, but no data is being passed
I used
local network: [network] 172.16.85.1/30
remote network [address] 172.16.85.2

I used the same on both sides. Is that correct, or should I make one address .1 and the other .2

Both have interfaces (interfaces/assignments/add)
Both have static routes, each using the assigned interface gateway.

As I mentioned, Status/IPsec on both pfSense boxes indicates that the tunnels are 'established'. but when I try to ping from one side to the other, I get no reponse.

I have an IPsec firewall rule that passes all IPV4 protocols.
The doc mentions that firewall rule processing can be confusing.
Do I need to create another IPsec firewall rule?

Is there a step-by-step how-to on setting up VTI IPsec connections between a pair of pfSense boxes?

Thanks!
