How to redirect DNS requests to custom resolver.
Hi, everyone.I am trying to override dns resolver settings in my app.I used NEVPNManager to install a personal vpn and then used onDemandRules to set specific dns servers.So far my code works for some domains.Below is my code.When I put "*.com" in matchDomains, it works perfectly.But what I wnat to do is to redirect all dns queries to specific dns server.I tried empty matchDomains([]) and empty string([""]).I also tried wildcard expression like ["*"] and ["*.*].So far I had no success.It's been a few days and I still can't figure it out.Can anybody tell me what I am missing here?Thanks in advance.let manager = NEVPNManager.sharedManager() manager.loadFromPreferencesWithCompletionHandler { error in if let vpnError = error { print("vpn error in loading preferences : \(vpnError)") return } if manager.protocolConfiguration == nil { let myIPSec = NEVPNProtocolIPSec() myIPSec.username = "username" myIPSec.serverAddress = "server address" myIPSec.passwordReference = self.getPersistentRef() myIPSec.authenticationMethod = NEVPNIKEAuthenticationMethod.SharedSecret myIPSec.sharedSecretReference = self.getPersistentRef() myIPSec.useExtendedAuthentication = true manager.protocolConfiguration = myIPSec manager.localizedDescription = "myDNS" let evaluationRule = NEEvaluateConnectionRule(matchDomains: ["*.com"], andAction: NEEvaluateConnectionRuleAction.ConnectIfNeeded) evaluationRule.useDNSServers = ["***.***.***.***"] let onDemandRule = NEOnDemandRuleEvaluateConnection() onDemandRule.connectionRules = [evaluationRule] onDemandRule.interfaceTypeMatch = NEOnDemandRuleInterfaceType.Any manager.onDemandRules = [onDemandRule] manager.onDemandEnabled = true manager.enabled = true manager.saveToPreferencesWithCompletionHandler { error in if let vpnError = error { print("vpn error in saving preferences : \(vpnError)") return } } } }
