Allocation of computer science … Smooth wall hack this stupid filter …?

So our professor gave us a surprise assignment when he knows that everything can easily navigate and filter normal school, but now the school has smoothwall "filter. Our test is to try to get beyond this, then let him know how we did. I will not lie. This is one medium piece of garbage. I have tried every trick in the book and can not fool the filter. Nosence addon I tried to URLs like apple.com / es /? Dog = nonos point is nothing is working. I can not even close to a proxy in sight, so I'll play humble and confess. I can not beat this guy. So I hope it's a smart person out there who can tell me how to beat him and then I get a brand can bond to my semester if I can explain how the exploitation of works. I hope someone can help me and thanks in advance.
