maxima problem



I am using maxima behind a firewall. I try the following things without
having success in ruuning maxima in windows XP service Pack 3.

 

1)      I set the proper maxima path in the windows EP mode,

2)      I reise the privileges to maxima engine and the the tcl
interface.

3)      I free the ports 4008 for the pipe connection in all the
firewall settings. 

 

Despite this, maxima is still not running giving the error: " Time for
connection exceeding".

 

Does any of you was successful to get maxima running through the
sockets(pipes) in windows xp? 

 

Could some one help me?

 

Thanks in advance.
