I have seen so many thread regarding this, but didn’t get any answer properly.

I connected using headless slave agent and put HOST:PORT in advanced setting of configuration of slave. Master is linux and slave is windows 7.

    =================================

    Since you are having problems with the public IP & DNS, can you make sure that routing for the public IP and DNS is allowed on your network. Just to be sure this is not a firewall issue. Are you on a corporate network? In that case, your corporate firewall may be blocking certain ports on all IP addresses.
