Hi baptiste, I think the requirements have been confused, the services are separate, but must fail together, if that makes sense, don't worry, it has taken me weeks to get the requirements clear from the project, but traffic to port 80 comes from an external source, and traffic to port 8080 is from an internal service bus. In any case, the config works as expected (until the project comes up with a new requirement), I've taken your advice on the tcp-check on board and will amend the config.
Thanks again for your help.
