Do I have to configure BTMM on my MacBook to?
If I am on a remote place, I can access TC using Air Port program, right?
Yes, there are details on setting up BTMM on the Mac..

There is plenty of angst involved of course..

For all kinds of issues that crop up.
Airport utility may not work.. in fact it is unlikely to since it is using a port not forwarded.
You are accessing files.. nothing else.
iPAd: There is a software (GoodReader) able to acess with AFP, but when I enter my IP adress (found over whatsmyip.com) as URL-Adress it doesnt work. It only works in WLAN inside with lokal IP adress. Any more hits??
Thank you.
As stated I am ipadless.. and not able to test any setup of any software.. you must google yourself.
Are you entering the address correctly.. ie
AFP://publicIPaddress
Do you have the sharing disk over WAN checked in the airport utility? See on the disks page of the utility. You will not be able to access it without that..
It is also a chance that enabling BTMM could stop direct access such as you are attempting with the ipad from working. Turn off BTMM before you start trying to access with ipad. It is totally different.. !!
