Tunnel settings allow you to fine-tune how RAGE establishes and maintains its secure connection. While the default settings work for most users, adjusting these options can help resolve connectivity issues or optimize performance for your specific network environment.
Network Stack
The network stack determines how RAGE processes network traffic on your device. RAGE offers two options:
| Stack | Description | Best For |
|---|---|---|
| System | Uses iOS native networking. Fast and battery-efficient. | Most users, stable networks |
| gVisor | User-space network stack with enhanced compatibility. | Complex networks, connection issues |
Recommendation: Start with System. If you experience connection drops or cannot establish a connection, try switching to gVisor.
IP Version
This setting controls which Internet Protocol version RAGE uses for the tunnel connection.
| Option | Description |
|---|---|
| Dual Stack | Uses both IPv4 and IPv6 simultaneously. Recommended. |
| IPv4 Priority | IPv4 with fallback to IPv6 |
| IPv6 Priority | IPv6 with fallback to IPv4 |
Recommendation: Use Dual Stack for maximum compatibility. It automatically handles both IPv4 and IPv6 traffic through the RAGE tunnel.
MTU Size
MTU (Maximum Transmission Unit) defines the largest packet size that can be sent over the network. Think of it as the size of envelopes used to send your data.
| MTU Value | Description | Use Case |
|---|---|---|
| 1400 | Default value. Balanced for most connections. | Home Wi-Fi, mobile data |
| 1280 | Smaller packets. More reliable on problematic networks. | Unstable connections, VPN-over-VPN |
Common symptoms of MTU issues:
- Connection establishes but pages don't load
- Downloads start but stall midway
- Video streaming buffers constantly
- Some websites work while others don't
Recommendation: Keep the default 1400. If you experience the symptoms above, try lowering to 1280.
How to Configure
- Open RAGE and go to the Settings tab
- Tap Tunnel in the Advanced section
- Select your preferred Network Stack
- Choose the IP Version for your network
- Adjust MTU if needed
- Reconnect to RAGE for changes to take effect
Note: Changes to tunnel settings require reconnecting to RAGE. If you're currently connected, disconnect and connect again to apply the new settings.
Troubleshooting
| Problem | Try This |
|---|---|
| Can't connect at all | Switch to gVisor stack |
| Frequent disconnections | Try gVisor or lower MTU to 1280 |
| Slow speeds | Use System stack with Dual Stack |
| Pages don't load when connected | Lower MTU to 1280 |
| Some sites don't work with IPv4/IPv6 Priority | Switch to Dual Stack |
| IPv6-only network issues | Switch to Dual Stack or IPv6 Priority |
