A proxy mode can look simpler, while TUN offers deeper system coverage. The right choice depends on application behavior, routing needs, and compatibility. For users checking the clash 官网, understanding these traffic paths makes configuration decisions clearer. ClashVerge supports both approaches, but each serves a different purpose. System Proxy suits applications that respect operating-system proxy settings. TUN reaches traffic that bypasses those settings, creating broader coverage.
System Proxy keeps routing lightweight
System Proxy changes the operating system’s proxy configuration. Supported applications then send requests through the selected proxy service. This approach consumes fewer resources and keeps networking behavior easy to inspect.
For browsing, messaging, and other proxy-aware programs, System Proxy offers a clean solution. It also reduces interference with applications requiring direct connections.
TUN reaches traffic beyond proxies
TUN creates a virtual network interface for system traffic. Applications do not need built-in proxy support to benefit from routing.
That broader capture makes TUN useful for games, launchers, and background services. However, broader interception can require extra permissions and careful rule management.
Which mode suits everyday browsing?
For ordinary desktop use, System Proxy remains the simpler option. It avoids unnecessary network interception while covering common applications.
A practical choice looks like this:
- Browsers can use System Proxy directly.
- Messaging clients often work without extra tuning.
- TUN helps unsupported applications follow rules.
- Background services may need explicit routing decisions.
The choice should follow application behavior, not feature count.
When does TUN become worthwhile?
TUN becomes valuable when proxy settings cannot reach required traffic. In those cases, clash routing can extend beyond conventional application support.
Consider TUN when:
- A game ignores operating-system proxy settings.
- A launcher requires consistent rule-based routing.
- Network requests bypass configured application proxies.
- DNS handling needs broader system-level control.
- Multiple applications need identical routing policies.
TUN adds coverage, but configuration deserves greater attention.
Compatibility determines the safer option
System Proxy creates fewer moving parts. That makes troubleshooting easier when applications behave predictably.
TUN introduces virtual networking, which can affect DNS, local services, firewall rules, and application connectivity. For example, a local development tool might need direct access while browser traffic follows proxy rules. Explicit routing rules can preserve that separation.
A small setting can change network scope
The important distinction is traffic scope, not interface preference. System Proxy handles applications that cooperate with proxy settings. TUN captures a wider range of system traffic.
That difference changes troubleshooting priorities. When a browser works but a game fails, TUN may solve the coverage gap. When local services break after enabling TUN, narrower routing may offer the better fix.
Traffic scope decides the final choice
System Proxy is the cleaner starting point for proxy-aware software. TUN becomes more compelling when a launcher, game, or background service escapes proxy settings. That distinction turns a simple toggle into a routing decision: broader capture brings broader responsibility, especially when DNS and local services matter.
