Thanks, Matt!
Please check FB9174140.
My test servers are behind the VPNs. So I can not test your recommendation.

Thanks Matt!
Please let me add few more details, below is my code.
(void)configureDNSProxy {
ns_info(module, "DNS proxy configurations will be loaded");
[[NEDNSProxyManager sharedManager]
loadFromPreferencesWithCompletionHandler:^(NSError * __nullable loadError) {
if (loadError){
return;
}
NEDNSProxyProviderProtocol *tunnelProtocol = [[NEDNSProxyProviderProtocol alloc] init];
[tunnelProtocol setServerAddress:@"DNS Gateway"];
tunnelProtocol.providerBundleIdentifier = dnsProxyBundleID_;
[NEDNSProxyManager sharedManager].enabled = true;
[NEDNSProxyManager sharedManager].localizedDescription = @"DNS Proxy";
[NEDNSProxyManager sharedManager].providerProtocol = tunnelProtocol;
[[NEDNSProxyManager sharedManager] saveToPreferencesWithCompletionHandler:^(NSError * _Nullable savePrefError) {
if (savePrefError) {
return;
}
}];
}];
}
(OSSystemExtensionReplacementAction)request:(OSSystemExtensionRequest *)request
																		actionForReplacingExtension:(OSSystemExtensionProperties *)existing
																withExtension:(OSSystemExtensionProperties *)ext {
		return OSSystemExtensionReplacementActionReplace;
}
(void)requestNeedsUserApproval:(OSSystemExtensionRequest *)request {
}
(void)request:(OSSystemExtensionRequest *)request
didFailWithError:(NSError *)error {
}
(void)request:(OSSystemExtensionRequest *)request
didFinishWithResult:(OSSystemExtensionRequestResult)result {
[self configureDNSProxy];
}
(void) initializeDNSProxy {
				NSString *extensionIdentifier = dnsProxyBundleID_;
				dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);				 OSSystemExtensionRequest *req = [OSSystemExtensionRequest activationRequestForExtension:extensionIdentifier
																																													queue:queue];
				req.delegate = self;
				[[OSSystemExtensionManager sharedManager] submitRequest:req];
}
It is called [myobj initializeDNSProxy];
Is it correct code?
Thanks

Same reply was posted twice inadvertently, therefore removed it.

Thanks Matt and Eskimo!
Your suggestion helped me a lot.

Thanks Matt!
int main(int argc, char *argv[])
{
@autoreleasepool {
[NEProvider startSystemExtensionMode];
}
dispatch_main();
}
Does RunLoop work with dispatch_main()?
Anyway, SCNetworkReachabilitySetDispatchQueue works for me.
Thanks

Thanks for your reply!But Acitivety Monitor shows different Process id for each extension. Is it correct? Regards,Anand Choubey

Thanks Matt!Try using a different DNS server and see if you start getting traffic there...Sorry, I did not get your suggestion. How to use different DNS server in getaddrinfo?We do not have any access policy on machine. Or do I miss your point?I missed one strange point before:If Network extension is disconnected from Network Preferences, all the block calls returns with resolved IP address.Regards,
