Yes it does. You seem to have some very complex setup, I suggest to look into whether you send replies from the interface you expect them to. If you use wg-quick, maybe switch to just wg and set up manually and with careful intent of each action, as wg-quick might not have in mind some aspect of your setup. -- With respect, Roman
