Cisco Routers :: RV042 Firewall Page Settings / Interactions?

I have an RV042 which is being used as an interface to an ISP.The WAN address (public) is obtained via PPPoE.The LAN address (also public) is entered manually from an assigned block of public addresses.  This is the internet gateway for other publicly-addresses devices like firewalls, VPN devices, etc.
 
I have an RV042 to play with as will as one in production that I can access.Because the accesses are both through public addresses, I want to use https to access the device.  I've generated a number of questions as I'm not sure the behavior is understandable to me and maybe the behavior isn't even  consistent.
 
- If the firewall is Disabled, the https setting is still available.  So, presumably https will work with the firewall enabled or disabled?  Is that right?
 
- I take it that the Remote Management setting and port number are associated with the WAN port.  For example, can one set Remote Management ON with port 443 and still access via the LAN on port 80?  on port 443?
 
- If Remote Mangement is OFF then I presume that one cannot access the device through the WAN.  Yet, that seems to not be the case.  I wonder if the public addresses on this device affect this?
 
Well, I guess we might forget about the Port number and just ponder the following - Sort of a truth table:
 
 Remote OFF
    http...........WAN access: NO              LAN access:  YES
    https..........WAN access: NO             LAN access:  YES
Remote ON
    http...........WAN access: YES           LAN access:  YES
    https..........WAN access: YES          LAN access:  YES
 
This is what it would seem to me to be but it doesn't seem to work that way.
