func CreateIPRules ¶

func CreateIPRules(nl Netlinker, rules []*IPRule) error

Types ¶

type EncapType ¶

type EncapType string

const (
	GRE EncapType = "gre"
)

type IPRule ¶

type IPRule struct {
	Priority int

func NewIPRule ¶

func NewIPRule(priority, table int, srcnet, dstnet string) (*IPRule, error)

NewIPRule creates a new linux IP rule. The priority and table value ranges must be within 100 - 200 for no good reason other than we can't insert rules just anywhere and stomp on other system rules.

func (*IPRule) String ¶

func (r *IPRule) String() string

type Netlink ¶

type Netlink struct{}

func (n Netlink) RouteAdd(r *Route) error

RouteAdd adds a route to the kernel routing table via netlink.

func (Netlink) RouteGet ¶

func (n Netlink) RouteGet(ip net.IP) ([]*Route, error)

RouteGet retrieves a route from the kernel routing table via netlink.

func (Netlink) RuleAdd ¶
