Functions

func ConfigureRoutes

func ConfigureRoutes(cfg *config.Config, ext dep.Dependencies) error

func FormatIptablesCommands

func FormatIptablesCommands(commands [][]string) []string

func HandleDNSUDP

func HandleDNSUDP(
	ops Ops, iptables *builder.IptablesBuilder, ext dep.Dependencies,
	cmd, proxyUID, proxyGID string, dnsServersV4 []string, dnsServersV6 []string, captureAllDNS bool)

HandleDNSUDP is a helper function to tackle with DNS UDP specific operations. This helps the creation logic of DNS UDP rules in sync with the deletion.

func SplitV4V6

func SplitV4V6(ips []string) (ipv4 []string, ipv6 []string)
