You have to forward your ports and it depends on your router or modem. You can find instructions here: »
portforward.com/default.htmBy the way, if you are using the SSH Tunnel, it won't matter if your ports are forwarded locally on your pc. You will essentially still have your listening ports blocked since the listening ports are really on Acanac's server.
It doesn't really matter, since all this means is that you can't connect to other peers that are similarly blocked on their own listening ports.
However, if you only use the SSH Tunnel during throttling hours, then you may want to forward your ports so that you can potentially get the maximum number of connections during off-peak hours.
