info.magnolia.cms.filters.DispatchRules#DispatchRules creates hardcoded dispatcher rules.
Such rules are created for every filter.
Although you can provide N2B config to override the default settings, you would need to do it for every single filter.
More complex solution would take the default from server/filters/dispatchRules to every filter in the filter chain.
The easier solution would at least change the default for include, this is currently:

toMagnoliaResources = false;
toWebContainerResources = false;

and could be

toMagnoliaResources = true;
toWebContainerResources = false;

to be able use server side includes such SSI, CGI or possibly sitemesh.
