Functions

func MakeRuleSpecText

func MakeRuleSpecText(winRuleSpec *WindowsRuleSpec, validate bool) (string, error)

converts a WindowsRuleSpec back into a string for an iptables rule

func ReduceIcmpProtoString

func ReduceIcmpProtoString(icmpProtoTypeCode string, policyRestrictions []string) ([]string, error)

ReduceIcmpProtoString will look at policyRestrictions and return a rulespec substring for matching. represents the logic: "icmpProtoTypeCode and (policyRestrictions[0] or policyRestrictions[1] or...)""

func TransformIcmpProtoString

func TransformIcmpProtoString(icmpProtoTypeCode string) []string

TransformIcmpProtoString parses icmp/type/code string coming from ACL rule and returns a rulespec subsection
