Hi, you seem to be very knowledgeable about this stuff, so maybe you can help me, I have been struggling to get my PS4 to work with remote play which I think is not working as I have been using a mobile hotspot which has been stuck on NAT3 with no upnp I believe, it works for PS4 online gaming but I believe the NAT3 is limiting me from Remote play, I just purchased the Slate AX-1800 thinking this can hopefully fix this issue. I want to know how to open upnp and the ports maybe needed for PS4 derestrictions, I think I need to start with openwrt but I am not sure where is the best place to download from that is compatible with my device, I believe luci is already pre installed I am not sure if upnp is maybe already in here ? sorry for the long message I have just realised ive been typing away!
