I recently bought a PS5, I can connect to the internet easily, but some network features don't seem to work. When testing the network, the field labelled as NAT Type gives a "failed" error. I think it's an issue with the home network, because when I try to connect the ps5 to my phone hotspot, the nat type is type 2 as expected.
I can see that it is a common issue, but I haven't found a solution that works with a huawei hg659, I'm on a fiber to the building network.
@mtecle . Internet articles on PS5 NAT type refer to certain port numbers being forwarded in the router config.
You can use a port scanning tool on the internet to check if these ports are open.
Connect the PS5 through your phone. Use port scan tool to check if the TCP ports are open on PS5.
Connect the PS5 through the hg659 and do same checks.
If the two tests have same results, I can't suggest anything else to try.
I'm not sure I followed those steps right, but I didn't really find a solution that way.
What I did do, is changing the firewall level to LOW and that did the trick, I'm just wondering how secure the network will be that way though
