Dear all,

I have had MobileMe for quite a time now and been very satisfied with it but never got round to using Back to My Mac and now have decided to set it up.

When i turn on Back to My Mac it always comes up with a amber light and the problem:

Back to My Mac isn't working properly because it requires a router that supports NAT Port Mapping Protocol (NAT-PMP) or Universal Plug and Play (UPnP). Make sure your router supports one of these protocols is enabled.

I have a Draytek Wireless Router 2800 Series running back at my place and it always seems to come up with this issue. i have enable UPnP on the router but the problem doesn't seem to go away is there a way to set up (NAT-PMP) or how can i get this working?

Many Thanks

Lyon

Every router is slightly different in the interface when it comes to supporting NAT.  

Somethings you will need:
  1. You will need your user maul it is here ftp://ftp.draytek.com/Vigor2800/Manual/User_Guide_V3.2.zip
  2. The port number on which back to my mac Listens for traffic I believe it is UDP-4500 and TCP-443
  3. Your router's public IP that is provisined by your ISP.  Simple enough, just go to whatsmyip.org and it will be displayed
    • NOTE!! This IP is most likely dynamic and could change at any time.  Register for a free service such as dyndns.org.
    • Refer to page 75 of the user manual
  4. Once you have that info refer to page 174 of the manaul.

Which does your Router support?

I have not read the manual.  Check your manual and it should tell you which it supports.

I prefer L2TP but check this out www.microsoft.com/VPN
