But to use VPN I fisrt have to create a ddns, wright?

My router b) does not support ddns, router a) does. Can I configure the ddns on this router en do a port forward on router b) ?

the connection with the DS by http://internetip:5000 works but when I try https://internetip:5001 is does not ( it tells that the owner of the website didn't configure it wright. When I want to setup ddns in the DS it always gives me that the verification failes. The registration of the internetip for my chosen hostname failed

What do you mean by hanging your DS directly on the internet? off course your DS is placed in your local network. To reach it from outside the local network you can use different methods. do you mean I can not try to reach it by internetip:5000 ?? I think I will try the ddns like sbv3000 posted. Does the he ddns only have to be set up on the router b) ?

Connecting with the http://wanip:5000 is possible from inside the network. From outside the network : the internetip I assume that is the unique address I get and not some 192.168.X.X or 10.0.X.X , I assume I can find this by ipconfig/ all on my desktop? or in router b) I'am going to check this when I am home. What is setup ddns, how do I do this? Is this just enabeling ddns, I wil search for this?

I am totally NOT a computer wizard but like to get most out off things. I run the dsm 6.0.2-8451 v1.01 My DiskStation is placed behind 2 routers (witch I configured with port forwarding). I assume I can access the internet as I can download packages. When I try to create an external way to reach the DS it always say that this is not possible. I tried quickconnect - activate - but when I want to make an account it always gives a screen saying that the action I tried to perform is not possible due to an error somewhere. I also tried it when I placed my DS behind only 1 router but this gives the same errors. I did some reading and found that it would have to do something with the serial number off the device? trying to create the sinology account It would check the serial number of the DS to see if you have a real synology DS, is this so?? How can I create a (safe) external access to my DS?
