pfSense CE IPSec Possible Bug Accepting Any IPv4 Address

[0x00FE 0]

Hello,

I have three sites:

Site A (Main office):
Using pfSense appliance (22.01)
Static IP

Site B (Home):
Using virtualized pfSense CE on Proxmox (2.6.0)
Static IP

Site C (Warehouse):
Using old pfSense appliance/computer both using pfSense CE (2.6.0)
Dynamic IP

Site A and B are connected through IPSec, where Site B initiates the connection and Site A is (Responder Only).
Site A and C are connected though IPSec , where Site C initiates the connection and Site A is (Responder Only).

Site C tries to initiate a connection to Site B but is unable to finish phase 1.
Site B has "Remote Gateway" set to "0.0.0.0" but will not accept any connections unless the IP of Site C is specified.
Site A has no issue accepting connections from Site C with "Remote Gateway" set to "0.0.0.0", unlike Site B.

After several days of troubleshooting, what works is:
Manually set the "Remote Gateway" in Site B to the dynamic IP of Site C (Not practical)
OR
Use dynamic DNS and set the "Remote Gateway" in Site B to be the FQDN of of the dynamic DNS record of Site C.

It seems that the option of accepting "0.0.0.0" for "Remote Gateway" in IPSec phase 1 in pfSense CE is not behaving similar to the appliance, but I can be wrong or missing something.

I have deleted the tunnels and reconfigured them several times to ensure both sides have the same configurations, only the IP configuration makes it or breaks it.

If anyone can replicate and confirm similar behavior, it could be submitted as a bug.
