Not? I used once a command promt and telnet from windows xp to connect to the router where I accidentally killed winbox access for myself. Copy/paste worked… I mean cmd promt way (edit => mark => (select) Enter, edit => paste) if you were referring to this.
Oh… well, they have to be more generous to have p2p allowed 24/7. You see, many of them want to have a cheap equipment, cheap internet and all benefits of the internet. To have p2p over a day on 2.4 Ghz… no way 
Like I said before… €, $, £ (or what ever you have) and get connected on 5 Ghz and you’ll have allowed p2p all the time
