Different question (my second post in this topic and the title don't matter now. I take it double posting is not allowed, and since I have this topic I guess it's better if I use this one): while it does seem to connect (it shows me I'm connected, and of course the huge slowdowns I fixed by turning Synchronize off), it never gets further than trying, so I decided to just set up a static IP and port forwarded anyway. I succesfully set up a static IP and forwarded the right port for the PC that will host, but still the same (and note: I've succesfully port forwarded before, with the same router. So I know how it works). What couldve gone wrong?
