QueryTask and proxy problem -

I've constructed a query task that returns the number of points in a polygon. 
This query task works perfectly if the query is against an internal map service (map service on the same arcgis server as the proxy). 
However, if I set the query task to an external map service:

queryTaskWithin = new esri.tasks.QueryTask("");

but change nothing else about the query or query task, it fails with the following error:

Error: Unable to load /proxy/proxy.ashx? status:403

My proxy config shouldn't be the problem because - as I am on a test server, I've made it wide open, by setting ProxyConfig mustMatch="false". I didn't even need to include my internal map service in the proxy.config, and the query worked fine for that. 

Any ideas what could be going on?
