type ProxyMode 

type ProxyMode string

Currently, four modes of proxying are available total: 'userspace' (older, stable), 'iptables' (newer, faster), 'ipvs', and 'kernelspace' (Windows only, newer).

If blank, use the best-available proxy (currently iptables, but may change in future versions). If the iptables proxy is selected, regardless of how, but the system's kernel or iptables versions are insufficient, this always falls back to the userspace proxy.

	ProxyModeUserspace   ProxyMode = "userspace"
