@Csimmo in which case you will need to open and forward ports to the PS5 as explained here https://www.techadvisor.com/article/744513/how-to-change-your-nat-type-on-ps5.html.
There are two methods to forward ports on Sky hubs the first is for black hubs see https://helpforum.sky.com/t5/Broadband-Talk/How-to-set-up-port-forwarding/ba-p/2662260 on thecwhite hubs it is simpler use yhe My Sky app find the hub's advanced settings and follow the instructions. Which ports are required depends on the game youbwant to play.
