If you use a router that is not manufactured by Apple, verify that it supports NAT-PMP (NAT Port Mapping Protocol) or UPnP IGDv1 (Universal Plug and Play Internet Gateway Device). Also, install the latest firmware available for your router. Check the manufacturer's website for instructions and more information.
- Some routers (including integrated "all-in-one" models which also include a DSL or cable modem) may support NAT-PMP or UPnP technology, but it might not be enabled by default. In addition, these routers may have only a single setting to enable or disable UPnP, which may control UPnP IGDv1 and other UPnP protocols. If you aren't sure if your third-party router device supports NAT-PMP or UPnP, you can review the product documentation supplied with the router, or contact the manufacturer.
- If NAT-PMP or UPnP technology has been enabled on your router device and you can reach iCloud services, yet are unable to use Back to My Mac, check to see if a firmware update is available for your router.

If you can connect to other computers but they can't connect to yours:
- Make sure that you're not using a "double NAT" network configuration (where more than one router is providing Network Address Translation between your Mac and the Internet). While this may not affect the ability of your computer to contact others via Back to My Mac, it may prevent other computers from discovering or connecting to your computer.
- Some firewalls, such as at a large organization, may not allow some Back to My Mac connections. For example, you might not be able to contact your Mac at work from home, but you might be able to contact your Mac at home from work. Check with your organization's network administrator to see if the Back To My Mac service can access your computer(s) through the firewall.
