Where did you find this? And what does this mean if NAT is used ?

Hm, you have to keep in mind that I use NAT here.
cerezal is my ARM-based NAS which is server node, I do not use
it as client. Also, I have a client node here which does currently lots
of uploads, it will appear at the same IP. As far as I've seen,
NAT works transparently with all these things. I
have opened the firewall for incoming connections 
only for the TUB port.

I could switch the client node off some time if that helps
to track down things.
