OpnSense GUI from Any LAN?

[Smack2k]

I am in the process of setting up my OpnSense router.  I have a WAN and 2 LAN interfaces in the system, all currently set to use DHCP for an address.

When I boot up the Router with LAN1 plugged in, it gets a DHCP address from my current Router and I get the message the Web Gui is available on that IP.  However, if I load the Router with only LAN2 plugged in, it gets an IP Adress properly in the same subnet as LAN1 from the same DHCP Server, but I cant hit the web GUI on that IP.....

Is there a setting somewhere that says what LANs you can / cant access the GUI from? 

Both LANs Interfaces have Allow Any for Source and Destination.  I'd like to get this up on LAN2 as there are things I need to do on LAN1 that I cant do if the port is active or it will cause issues with my current network

Instead of what I mentioned above, I can just ask this question...

When I turn off DHCP to LAN1 as the Sub-Interfaces / VLANs attached to LAN1 will all be active and online, where will I go to hit the OpnSense GUI as its seemingly attached to LAN1's IP Address....
