When there's a proxy server and a firewall a common configuration of the firewall is to disallow any connections that don't pass through the proxy. If that's the case on your network then you won't be able to open a connection to an Internet host via code with out a change in the firewall configuration. In that environment you are limited to connections that pass through the proxy.

If you have a valid reason to connect directly to an Internet host you may be able to get your local network administrators to modify the firewall config.
