Back To My Mac Manual Port Forwarding

Posted on by



To best answer your question on whether the two are 'mutually exclusive,' let take a look at how Back to My Mac (BTMM) basically works.

BTMM - General Requirements

If you need to set up port forwarding with the VBoxManage command instead of using the graphical interface, you’ll find instructions for doing so in VirtualBox’s manual. To forward ports in VirtualBox, first open a virtual machine’s settings window by selecting the Settings option in the menu. Select the Network pane in the virtual.

  • OS X Leopard 10.7.3+
  • Active iCloud account. Each Mac & the AirPort router, that will be relying on BTMM, needs to be configured with the same account.
  • A publicly reachable IP address for your router.
  • A router that supports either NAT-PMP or UPnP. For AirPorts, be sure it is running 7.6.1+ firmware.
  • BTMM uses TCP port 5354 and UDP ports 4500 & 5353 for communications.

  1. How can I open access to port 8080 from the outside world (private lan) on my Mac OS X Lion? I'd like to access a webpage that's running on my lamp stack on my mac (zend server ce) from within the lan. I can access port 80 just fine. Port 8080 is blocked on the other hand. I've also disabled the firewall.
  2. To set up port forwarding for your Mac, you need to (a) determine your NAT type, (b) get a static IP address for your Mac, (c) determine your game’s port number and type, and (d) change your router’s NAT type. Determine your NAT type To see if your NAT settings are affecting your gaming, first determine your NAT type.
  3. It is possible to use the Port Forwarding feature on the WAN2 interface UDM-Pro when using the Classic Web UI. Navigate to the Settings Routing & Firewall Port Forwarding section and create a Port Forwarding rule or modify an existing one. Afterwards, you can select the WAN interface to be WAN1, WAN2 or both.

BTMM - Basic Communication Flow

  • For a computer connected to the Internet via a router, BTMM 'asks' the router for its configuration information. For a router, like your AirPort, that uses NAT-PMP, BTMM will ask the router to assign arbitrary public ports. In turn, the router will provide these port assignments (& the router's Public IP address) back to BTMM.
  • BTMM then sends this information to the iCloud account. In background iCloud updates a special set of DNS entries to be used by BTMM. These entries are then made available to all BTMM clients using your iCloud account. When a computer, with BTMM enabled, uses your iCloud credentials, it automatically retrieves a list of all other computers/routers that are registered with the same account. All these devices should then appear under the SHARED section of the Finder.
  • When attempting to connect to a remote computer (or router), BTMM creates a secure connection to that remote device using the information from the iCloud account.
  • Once the connection is established, the devices can then communicate with each other.


So potentially, unless you are using Port Mapping for any of the ports BTMM uses, they should not conflict.
