Types ¶
type Config ¶
type Config struct {
LocalAddrs []netaddr.IPPrefix
Routes []netaddr.IPPrefix // routes to point into the Tailscale interface
DNS dns.Config
SubnetRoutes []netaddr.IPPrefix // subnets being advertised to other Tailscale nodes
SNATSubnetRoutes bool // SNAT traffic to local subnets
NetfilterMode NetfilterMode // how much to manage netfilter rules
}
Config is the subset of Tailscale configuration that is relevant to the OS's network stack.
type NetfilterMode ¶
type NetfilterMode int
NetfilterMode is the firewall management mode to use when programming the Linux network stack.
const ( NetfilterOff NetfilterMode = iota // remove all tailscale netfilter state NetfilterNoDivert // manage tailscale chains, but don't call them NetfilterOn // manage tailscale chains and call them from main chains )
func (NetfilterMode) String ¶
func (m NetfilterMode) String() string
type Router ¶
type Router interface {
// Up brings the router up.
Up() error
// Set updates the OS network stack with a new Config. It may be
// called multiple times with identical Configs, which the
// implementation should handle gracefully.
Set(*Config) error
// Close closes the router.
Close() error
}
Router is responsible for managing the system network stack.
There is typically only one instance of this interface per process.
