v2rayN: the desktop-first choice
v2rayN's main strength is bringing common desktop operations together in one graphical interface. For a first setup, follow this order: add a subscription, update it, select a server, enable the system proxy and check the connection. When managing multiple subscriptions, organize groups and update order to avoid selecting the wrong server from a mixed list.
Once you move into advanced configuration, v2rayN is also suited to routing rules, DNS, logs, core management and TUN. Its rules interface helps you inspect matching order, but as the rule set grows, you still need to understand how domains, IPs, inbounds and outbounds relate. TUN is useful when more desktop application traffic must be intercepted. Before enabling it, confirm administrator permissions, local ports and DNS settings so basic connection issues are not mixed with TUN issues during troubleshooting.
If you only need a browser and a few applications that follow the system proxy, start with the system proxy. After confirming that standard mode is stable, decide whether TUN is necessary. This keeps the number of variables small and makes configuration errors easier to locate in the client logs.
