erm well the reason i use proxy is because i want to play safe and i want to have my IP address masked when downloading.

In fact i use tunneling software rather than those free proxies as it hard to find a good one. i got two tunneling software that is http-tunnel and secure tunnel and i use it with limewire and morpheus to test how well they work and
limewire work very well secure tunnel software whereas morphues dont seem working with either of them....still trying to configure to make it work. i am trying to configure if http tunnel work well with limewire or not.

Btw if i am using limewire(free version) one, does it have a limit downloading/uploading speed?

As with proxy or no proxy my speed is around 5kbs/s to 20kbs/s.
