Docs Config Experimental Config

Experimental Config

These fields are for low-level network stack tuning. Most people don't need to touch them — only consider adjusting them if you run into specific network compatibility issues.

Example Config

config.yaml YAML

experimental:
  quic-go-disable-gso: false
  quic-go-disable-ecn: false
  dialer-ip4p-convert: false

Field Reference

quic-go-disable-gso

Disable GSO (Generic Segmentation Offload). Some virtualized environments or NIC drivers don't handle GSO well — try disabling it if QUIC-based protocols (Hysteria2/TUIC, etc.) have connection issues.

quic-go-disable-ecn

Disable ECN (Explicit Congestion Notification). Another option to try when troubleshooting QUIC protocol connection issues.

dialer-ip4p-convert

Enable IP4P address conversion — only needed in specific network environments (such as certain ISPs' IPv4/IPv6 conversion gateways).
