Before connecting your PS4 to your home network I would advise blocking the PSN servers, this will stop the PS4 from downloading the latest system update from the PSN which it will do automatically, the good news is that the PS4 will not automatically install updates unless you have set it to do so when sleeping in the system settings. Even if the PS4 has downloaded an update, once PSN access is blocked it will not nag you about installing an update. How exactly you will block access to the PSN depends on your router, basic routers provided by your ISP might well not be able to do this. Below are the following hostnames PS4's on firmware 1.76 use to access various parts of the PSN, addition hosts could well be present in later PS4 updates, however I only have one PS4 on 1.76 to test with. You need to block the following host names on your router, this will stop the PS4 from talking to any of Sony's server, however still allow internet access: It will be impossible for me to show you exactly how to do this on your home network, as many 1000's of different routers / network setup's exist. How Did I Block My PS4 From Accessing The PSN On My Router? First I have my router set to assign my PS4 a static IP address, this means my PS4 will always have the same IP address on my network. I have then added the PS4's IP address on my local network to an list (alias) called PS4 consoles. I have then created another list which contains all the host names for the PSN above, this is called PS4 Servers. Finally I have created a rule which blocks all IPV4 traffic from the PS4 Consoles going to the PS4 servers, as can be seen below: The end result is my PS4 still has internet access, it just can't talk to Sony's servers. I'm using pfSense as my router / firewall, this can run on an old PC with two network cards. pfSense can be downloaded for free here: pfSense download Conclusion: I hope that gives you some idea how you can go about blocking internet access on your PS4, yet still keep the PS4 connected to your home network. It's impossible to create a guide that will work for everyone, due to their been many many 1000's of different home network setups out there. If all else fails setting an invalid DNS server which doesn't exist is a great quick solution.
