Mobile Me - Back to my Mac

I have been trying to setup the Back to my mac function using a mikrotik routerboard. I have played with the uPNP function but am still unable to get it to work. Has anyone sucessfully set this up? Here is a screenshot of what the setup is telling me. Thanks. I am on RouterOS version 3.13.

to enable uPnP on routerOS use this command:

/ip upnp set enabled=yes



I have played with the uPNP function but am still unable to get it to work

Yep, played with every iteration of that and it gives me the same message.

This still does not work! Any help would be great.

Thanks
