Port 500 refusing connection on RV320

[Deddo]

After configuring an IPSec gateway to gateway of RV320, phase 1 has refused to go through, error from the connecting device PFsense shows that port 500 refused the connection.

My understanding is that port 500 is opened by default on RV320, why is it now refusing connection?

i would check the config again, also check the Logs in RV side ?
