Is there any way to consume a webservice what is currently behind an authenticated proxy server?

Your best bet would be to WhiteList salesforce's IP adresses on the proxy.
in the below link you can find the ranges for each Datacenter:

You would not like to have your application to break if the username and password credentials from a proxy would expire right? ;)
Good Luck.
