Bypassing a firewall with a socks5

[DomainEmpire.com]

I need to bypass my own firewall (a router of my domestic network) to be able to use Kazaa and other peer2peer programs ...
I don't know exactly what happened but, since I changed provider and a technician configured my pc with the new settings, I'm unable to use Kazaa (the search function appear disabled and it doesn't connect).

Now, an expert would easily solve the problem considering I'm the only "administrator" but this's not my field so would be much easier installing a socks5 I think ...
I'm a bit new to this field, I only know I need a socks5 but nothing more ;-)

Any idea and suggestion to help me to get around this problem, would be highly appreciated, thanks.

Proxy....

Yes I know that a socks5 is a proxy but I don't know where finding a cheap proxy easy to install and configure which should not create conflicts with the other programs.
