But this will make admin have to put redirect from the cms to everything under the node. Is there no other way? Perhaps modifying the web config?

Then you have to do it in code by creating a filter and use it on application started.

ProductRedirectFilter.cs

public class ProductRedirectFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (filterContext.HttpContext.Request.Url.ToString().Contains("products"))
        {
            // find more efficient ways to check if url contains products
            // use regex to check for string after products/..../.../

            filterContext.Result = new RedirectResult("www.domain.com/products");
        }
    }
}

Add the filter in another class FilterConfig.cs

public class FilterConfig
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new ProductRedirectFilter());
    }
}

Then on your application started event handler:

public class YourApplication : ApplicationEventHandler
{
    protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        base.ApplicationStarted(umbracoApplication, applicationContext);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    }
}

Not tested though, but should work.

will try and update tomorrow at work. Thanks!
