Question

我的应用程序使用IPv4实现了NEPacketTunnelProvider隧道。隧道系统可以完美运行，但在IPv6中无法正常运行。

我正在尝试使VPN应用适应ipv6环境，但是我不知道如何开始，请告诉我怎么做。

这是我的代码：

let newSettings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: "127.0.0.1")
let ip = "32.432.53.1"
let subnet = "10.3.21.1"
newSettings.ipv4Settings = NEIPv4Settings(addresses: [ip], subnetMasks: [subnet])
newSettings.mtu = 1432
newSettings.ipv4Settings?.includedRoutes = [NEIPv4Route.default()]
newSettings.ipv6Settings?.includedRoutes = [NEIPv6Route.default()]
newSettings.dnsSettings = NEDNSSettings(servers: ["8.8.8.8"])

let endPoint = NWHostEndpoint(hostname: "12.432.55.22", port: 9090)
var session = self.createUDPSession(to: endPoint, from: nil)

self.session?.writeDatagram(newData, completionHandler: { (error) in

})
self.session?.setReadHandler({ (newPackets: [Data]?, error: Error?) -> Void in

}, maxDatagrams: NSIntegerMax)

Answer 1

newSettings.ipv4Settings = NEIPv4Settings(addresses: [ip], subnetMasks: [subnet]) newSettings只有ipv4Settings

您应该添加以下行：

let ipv6Settings = NEIPv6Settings.init(addresses: ["fe80:1ca8:5ee3:4d6d:aaf5"], networkPrefixLengths: [64])
newSettings.ipv6Settings = ipv6Settings

但是我的演示的UDPSession setReadHandler没有涉及

如何在ipv6环境中使用NEPacketTunnelProvider
