Latency Comparison

Direct vs Relay β€”
the difference is real

Both connection types work great, but a direct connection eliminates the server hop for noticeably lower latency.

Direct Connection

< 5ms
round-trip latency

Data flows directly between your devices. No server in the middle. Ideal for gaming, design work, and anything interactive.

Relay Connection

30–100ms
round-trip latency

Data is routed through a secure relay server. Fully encrypted and optimized for the fastest possible relay path. Works everywhere.

Why am I on relay?

A relay connection happens when your devices can't reach each other directly. This is usually caused by:

Devices on different networks (e.g., mobile data vs. Wi-Fi)
Router firewall blocking peer-to-peer connections
Strict NAT type on your network
Corporate, hotel, or university network restrictions

Same Wi-Fi Network

If both devices are on the same Wi-Fi network, a direct connection should happen automatically. If it doesn't, try these steps:

1
Make sure both devices are connected to the same Wi-Fi network
2
On your Mac, check System Settings β†’ Network to confirm the Wi-Fi name matches
3
Disconnect and reconnect in Remio
πŸ’‘

If using a mesh router (e.g., Google Nest, eero, Deco), ensure both devices are on the same SSID band. Some mesh systems isolate devices across bands.

Different Networks (Port Forwarding)

When connecting from a different network (e.g., from cellular to your home Mac), you may need to set up port forwarding on your home router:

1
Find your Mac's local IP address in System Settings β†’ Network (e.g., 192.168.1.100)
2
Log in to your router admin page (usually 192.168.1.1 or 192.168.0.1)
3
Navigate to Port Forwarding settings
4
Forward UDP ports 49152–65535 to your Mac's local IP
5
Save and reconnect in Remio
πŸ”’

Remio uses random high ports (49152–65535) for media streaming. Forwarding this range allows direct connections while maintaining security.

Ports to Forward
UDP 49152 – 65535 Remio Streaming (Video/Audio)

Firewall Settings

Make sure your Mac's firewall isn't blocking Remio:

1
Open System Settings β†’ Network β†’ Firewall
2
Click Options… (or Firewall Options)
3
Add Remio Host to the allowed apps list
4
Ensure "Allow incoming connections" is checked for Remio

Still on relay?

Some networks β€” hotels, offices, universities β€” have strict firewalls that block peer-to-peer connections. In these cases, relay is the best available option. Remio optimizes the relay path for the lowest possible latency, so your experience stays smooth.
