Well okay, it is a pity. You could just have a look at your router page, it's actually generally very self-explanatory, and as I understand it opening an arbitrary port doesn't represent a security risk at all (you already have quite a few open ports, e.g. one for the internet, one for e-mail). But no worries if you're not comfortable with it.

I wish I could host, but my computer's by my bed and ridiculously loud, so I could never leave it on all the time.
