As long as all the devices connect to the second router and nothing connects directly to the Virgin hub (except the second router obviously...) then all the devices are on the same network (provided by the second router) and will see each other with no issues. Port forwarding will be annoying though, I usually use that for one thing on my network to be connectable from the outside but I'm not travelling now so I can manage for a while without it.
