Chiaki-ng Remote Play Over the Internet (Outside Home) – WAN Setup
Yes — chiaki-ng can stream your PS5 or PS4 over the internet when you are away from home. Register the console through PSN (not just local discovery), and v1.10.0’s improved NAT port guessing and hole-punching will usually connect you with zero router changes. If it does not, manually forwarding ports 9295–9297 (UDP/TCP) is the reliable fix.
How Remote-Over-Internet Works
On your home network, chiaki-ng finds the console with local UDP discovery. Away from home, it instead reaches your console
through PlayStation Network registration: the app and the console coordinate through PSN (the “senkusha” handshake),
then punch a direct UDP path through your router’s NAT. Version v1.10.0 significantly improved this path with
configurable NAT port guessing and hole-punching fixes, so many setups that previously needed manual port forwarding now just work.
Setup Steps
- Register at home first.
Complete the normal setup guide on your home LAN, making sure the console is registered via your PSN Account ID (not only local discovery). - Try connecting from outside.
From another network, open chiaki-ng and double-click the console. With v1.10.0’s NAT improvements, this succeeds for most home routers with no changes. - If it fails: forward ports manually.
Give your PS5/PS4 a fixed LAN IP (DHCP reservation in your router), then forward these ports to it:
| Ports | Protocol | Forward to |
|---|---|---|
| 9295, 9296, 9297 | UDP and TCP | Your console’s LAN IP (e.g. 192.168.1.50) |
UPnP can do this automatically if your router supports it, but manual forwarding is more reliable. After forwarding, restart chiaki-ng and try again.
that no client-side setting can punch through. If port forwarding is impossible on your network (e.g. phone tethering on certain carriers),
remote play from that network may simply not work — this is a network limitation, not a chiaki-ng bug.
Hotel & Campus Wi-Fi: An Honest Note
Hotel, campus, and office networks often block the ports Remote Play needs, or trap you behind a captive portal login page.
In that specific situation a VPN can help — not by making the stream faster (a VPN always adds latency), but by tunneling
past the blocked ports so the connection can be established at all. If the network itself is fast, a VPN-based connection can still be playable.
Frequently Asked Questions
Do I need port forwarding to use chiaki-ng away from home?
Usually not anymore. Since v1.10.0, chiaki-ng’s improved NAT port guessing and hole-punching connect through most home routers with zero configuration. Only set up manual port forwarding (9295–9297 UDP/TCP) if the automatic connection fails.
Which ports does chiaki-ng need for remote play over the internet?
Forward ports 9295, 9296, and 9297 for both UDP and TCP to your console’s LAN IP address. Give the console a fixed IP (DHCP reservation) first so the forwarding rule keeps working after reboots.
Why does remote play work at home but not on hotel Wi-Fi?
Hotel, campus, and office networks commonly block the UDP ports Remote Play needs, or require a captive-portal login that game consoles and streaming apps cannot complete. A VPN tunnel can bypass blocked ports in this specific scenario — it will not make the stream faster, but it can make it connect.
Does using a VPN improve chiaki-ng streaming quality?
No — a VPN adds an extra hop and always increases latency. The only honest reason to use one with remote play is to get around a network that blocks the required ports (hotels, campuses, some offices). On your own home network, never use a VPN for streaming.
Is it safe to forward ports to my PlayStation?
Forwarding 9295–9297 only exposes your console’s Remote Play service, which still requires your PSN Account ID and registration to connect. Keep your console firmware updated. If you prefer not to open ports, try UPnP first — and remember v1.10.0 often needs neither.
