func NewEgressGateway

func NewEgressGateway() (*EgressGateway, error)

NewEgressGateway is a constructor for EgressGateway interface

func (*EgressGateway) AddStaticIptablesRule

AddStaticIptablesRule adds iptables rule for SNAT, creates source and destination IPsets. IPs can then be dynamically added to these IPsets.

func (*EgressGateway) DeleteStaticIptablesRule

func (d *EgressGateway) DeleteStaticIptablesRule(routingID string, routingName string, tableName string, sourceIPs []string, destinationIP string, egressIP string) error

DeleteStaticIptablesRule clears IPtables rules added by AddStaticIptablesRule

func (*EgressGateway) Setup
