Hello all

                I am using VNC to capture a computer through a webpage, but
some clients can 4t do it. I think the problem can be that they don4t have a
public ip or that they have a firewall. Do you know if this can be that way
and if it4s so, how can I solve it? Another posibility is related to having
or not the Java console installed can this be the problem?
