*idea* I just was on the toilet and had an Idea. Yay me.
It would be very interesting how this Download forwarding works.
IF it works in such a way that it redirects incoming port 80/http requests to another Server transparently and directly, while that other Server then opens the back-channel to the requesting Host (me) then i think i know what is causing those problems.
My firewall's NAT algorithm will not let it in. It will only allow the back-channel to be opened from the Host that was requested to open one.
This theory seems to fit well.
If you do not know wheter that is how DL redirection operates i can run some low-level tests.
