I'm working on an IPSec VPN solution for macOS. I've managed to get a VPN configuration installed via NEVPNManager and everything works. Except, my requirment is to disconnect the VPN when mac goes to sleep. Below is the IPSec profile which I am using.- (void)setupIPSec{ [self configVPNKeychain]; NSData *passwordData = [self persistentReferenceForSavedPassword:@"username" service:kPasswordReference account:@"account" description:@"login"]; NSData *sharedSecretData = [self persistentReferenceForSavedPassword:@"54343333" service:kSharedSecretReference account:@"account" description:@"IPSec Shared Secret"]; // config IPSec protocol NEVPNProtocolIPSec *p = [[NEVPNProtocolIPSec alloc] init]; p.username = @"username012134"; p.serverAddress = @"ipsec.route.com"; // get password persistent reference from keychain p.passwordReference = passwordData; p.authenticationMethod = NEVPNIKEAuthenticationMethodSharedSecret; p.sharedSecretReference = sharedSecretData; p.useExtendedAuthentication = YES; p.disconnectOnSleep = YES; // This is were I am setting YES to disconnect the VPN connection when on Sleep. [NEVPNManager sharedManager].enabled = YES; [NEVPNManager sharedManager].protocolConfiguration = p; [NEVPNManager sharedManager].localizedDescription = @"VPN";}Can anyone please guide me.
