Ip fragmentation and some network features

[Cox]

Ip fragmentation and some network features might be restricted to my playstation 4

@Cox what makes you come to this conclusion. PS4 units normally work well on Sky networks but of course issues like poor wifi can and do cause issues.

I'm using a ethernet cable to connect to my playstation to the sky max hub

@Cox ok so we can exclude wifi issues but you did not answer the question as to the symptoms or errors you are experiencing.. Not knowing what router/hub you have I will assume it is a Sky hub.

However guessing you maybe referring to packet fragmentation you may want to take a look at the mtu value on the PS4 to automatic to see if that solves anything otherwise experiment with settings of 1492. There have been issues around "NAT type" reported  enabling uPnP on the hub is sensible (unusually the setting for uPNP is within the web interface on the white hubs not the app). Enabling UPnP on the white hub should change the MAP-T IP address sharing from a 8:1 to a 1:1 which may help again depending on the issues you have black hubs do not permit Sky to use MAP-T..

While you could place the PS4 in the DMZ personally I would not be happy leaving any device without firewall protection..
