If your country itself is blocking those ports, it has it's reasons (right or wrong) and, chances are they have somebody (or more likely, several somebodies) watching for people trying to circumvent their security. Attemping to circumvent it is likely to land you in a world of grief. You know your government a whole lot better than I do (considering you didn't specify which country, I have no idea where you are) and likely have a better understanding of the consequences of getting caught hacking their network.
Your best, and safest, bet is to contact your government and explain your problem to them. If it's legitimate, you might find them helping you.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
