I have two sites A and B.

In site A, I have:

FW_A (OPNsense) with WAN XXX.XXX.XXX.XXX and LAN 10.0.10.254/24
SERVER_A with IP 10.0.10.1/24 and GW 10.0.10.254
In site B, I have:
FW_B (OPNsense) with WAN YYY.YYY.YYY.YYY and LAN 10.0.20.254/24
SERVER_B with IP 10.0.20.1/24 and GW 10.0.20.254
Site A and B are connected via IPsec (basically default setup).

From SERVER_A, I can ping FW_B and SERVER_B (no problem here).
From SERVER_B, I can ping FW_A and SERVER_A (no problem here).

The problems that I have

from FW_A, I cannot ping FW_B and SERVER_B
from FW_B, I cannot ping FW_A and SERVER_A
How can I fix this?

Thank you very much.
