init(remoteNetwork:remotePrefix:localNetwork:localPrefix:protocol:direction:)
Creates a rule that matches traffic by remote network, local network, protocol, and direction.
Declaration
init(remoteNetwork: NWHostEndpoint?, remotePrefix: Int, localNetwork: NWHostEndpoint?, localPrefix: Int, protocol: NENetworkRule.Protocol, direction: NETrafficDirection)Parameters
- remoteNetwork:
An endpoint instance that contains the remote port and the remote address or network that the rule matches. This endpoint must contain an address, not a hostname.
- remotePrefix:
An integer that in combination with the address in
remoteNetworkspecifies the remote network that the rule matches. - localNetwork:
An endpoint instance that contains the local port and the local address or network that the rule matches. This endpoint must contain an address, not a hostname.
- localPrefix:
An integer that in combination with the address in localNetwork specifies the local network that the rule matches. The rule ignores this parameter if
localNetworkisnil. - protocol:
The protocol that the rule matches.
- direction:
The direction of network traffic that the rule matches.
Discussion
If the port string of remoteNetwork is 0 or the empty string, then the rule matches traffic on any port coming from the remote network. If remoteNetwork is nil, the rule matches any remote network.
If the port string of localNetwork is 0 or the empty string, then the rule matches traffic on any port coming from the local network. If localNetwork is nil, the rule matches any local network.
