Zuul timing out in long-ish requests

I am using a front end Spring Cloud application (micro service) acting as a Zuul proxy (@EnableZuulProxy) to route requests from an external source to other internal micro services written using spring cloud (spring boot).
The Zuul server is straight out of the applications in the samples section

@SpringBootApplication
@Controller
@EnableZuulProxy
@EnableDiscoveryClient
public class ZuulServerApplication {
    public static void main(String[] args) {
        new SpringApplicationBuilder(ZuulServerApplication.class).web(true).run(args);
    }
}

I ran this set of services locally and it all seems to work fine but if I run it on a network with some load, or through a VPN, then I start to see Zuul forwarding errors, which I am seeing as client timeouts in the logs.

Is there any way to change the timeout on the Zuul forwards so that I can eliminate this issue from my immediate concerns? What accessible parameter settings are there for this?

The properties to set are: ribbon.ReadTimeout in general and <service>.ribbon.ReadTimeout for a specific service, in milliseconds. The Ribbon wiki has some examples. This javadoc has the property names.
