I'm with Toucan, who has a "fair usage policy", which means I get 1 byte per second when using p2p.
Now, that doesn't seem particularly fair to me, when they market the package as "unlimited", then write a terms and condition which is about a few megabytes long.
I tried changing ports to random numbers between 80 and 60000, that didn't seem to work. I tried public proxy servers, which didn't work. I'm using a USB modem, so I'm not sure wether portforwarding is possible.
How do I get past this restriction?
