Thanks for your help Georg.
But today there is a disaster, some one hacked into my router and changed my password, some more, denied all out going traffic. My company network was down for the whole day. Bad luck is today I have an exam, just got time to reset the router at about 8 pm, finally get the router up in 9. I curse the people who changed my password.
My problem still persist, my need some further help from you guys.
