func NewDNSOptionsFromNetIp(ipp netip.AddrPort) (*DNSOptions, error)
func (*DNSOptions) AddrPort ¶
func (d *DNSOptions) AddrPort() string
func (*DNSOptions) ResolvedAddrs ¶
func (d *DNSOptions) ResolvedAddrs() string
func (*DNSOptions) String ¶
func (d *DNSOptions) String() string
type ProxyOptions ¶
type ProxyOptions struct {
Auth *proxy.Auth
IP string // just the ip
Host string // just the hostname (no port)
Port string // just the port number
IPPort string // may be a url or ip:port
Scheme string // http, https, socks5, pip
Addrs []string // list of ips if ipport is a url; may be nil
}
ProxyOptions define https or socks5 proxy options
func NewAuthProxyOptions ¶
func NewAuthProxyOptions(scheme, username, password, ip, port string, addrs []string) *ProxyOptions
NewAuthProxyOptions returns a new ProxyOptions object with authentication object.
func NewProxyOptions ¶
func NewProxyOptions(ip string, port string) *ProxyOptions
NewProxyOptions returns a new ProxyOptions object.
func (*ProxyOptions) FullUrl ¶
func (p *ProxyOptions) FullUrl() string
func (*ProxyOptions) HasAuth ¶
func (p *ProxyOptions) HasAuth() bool
func (*ProxyOptions) String ¶
func (p *ProxyOptions) String() string

type TunMode ¶
type TunMode struct {
// DNSMode specifies the kind of DNS traffic to be trapped and routed to DoH servers
DNSMode int
// BlockMode instructs change in firewall behaviour.
BlockMode int
// PtMode determines 6to4 translation heuristics.
PtMode int
}
TunMode specifies dns, firewall, xlat, and ip modes
func DefaultTunMode ¶
func DefaultTunMode() *TunMode
DefaultTunMode returns a new default TunMode with IP-only DNS capture and replay (not all DNS traffic but only the DNS traffic sent to [tcp/udp]handler.fakedns is captured and replayed to the remote DoH server) and with firewall disabled.
func NewTunMode ¶
NewTunMode returns a new TunMode object. `d` sets dns-mode. `b` sets block-mode. `pt` sets natpt-mode.
