His post is woefully empty of facts, leading to all sorts of theories.

HIs theory is that the ISP is port blocking him.
His ISPs response has two possibilities-- that he is using a dynamic
adress and thus never knows what the IP address is of his machine. Or
that the ISP blocks most incoming ports on dynamic addresses. But not
static. 

The above advice is pretty useless since the ISP will then simply block
all incoming abd outgoing ports (ie disconnect him), which will
accomplish what?

So the OP has to be a bit more forthcoming as what is happening.
