Sales force IP's

Hi, My org has a firewall which allows only sales force IP ranges to communicate with their servers..when I make a web service call to their service,it is giving me the following error.

 

System.CalloutException: IO Exception: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 503 Service Unavailable.

 

How do I know the ipaddress of the salesforce machine or instance thats routing my request to the end point location?

Is the proxy at the sales force server blocking me or the local proxy? How do I know whats going on..? Pls advise.

 

Thanks.

In the Setup->Help Menu you can find the IP Addresses if you search for it.
