The version tag of current system is: 11.5 Beta (20G5023d) After some time testing, not able to browse anymore although appproxy device is still connected and can still ping through.

Also, can you help indicate how to update in the tsi ticket? I would like to go on discussion fromTSI case 767665663, but don't know what is the link for it. Thanks in advance.

You can let the system handle all UDP flows. You can attempt to target a small subset of UDP flows and if you receive port 53 flows, you can proxy them. Proxying UDP flows is something that can be done without a crash. That is what I am trying at the moment. But when letting all udp traffic through with filter setting like below, within around three hours, network is gone like below. Crash might not happen though. ping apple.com ... Request timeout for icmp_seq 14745 ping: sendto: No route to host Request timeout for icmp_seq 14746 ping: sendto: No route to host I have tried both udp session and NWConnection for remote connection, same result. Any suggestion? for seg in 1...254 { if seg != 127 { hosts = [("\(seg).0.0.0", "0")] for host in hosts { let ep = NWHostEndpoint(hostname: host.0, port: host.1) let rule = NENetworkRule.init(remoteNetwork: ep, remotePrefix: 8, localNetwork: nil, localPrefix: 0, protocol: .UDP, direction: .outbound) rules.append(rule) } } }

Hi there, Following this topic, we managed to make both appproxy and dnsproxy work together at the same time, but have some constraints. Wonder if you can provide some help. Need uninstall extension each time before you run the application. It is with below command to control the extension. systemextensionsctl uninstall $DNSExtensionID $DNSExtensionName If start dnsproxy first, then only one network service is prompted and added without the one for appproxy. If start approxy first, both network service are added, but dnsproxy doesn’t work (as the extension access right problem). AppDelegate.swift:applicationDidFinishLaunching() { ...      // Start App Proxy     ProxyManager.shared().loadProxyManager(connect: true) {       ProxyManager.shared().addObserver {}       ProxyManager.shared().start() // Start the DNS Proxy DNSManager.shared().start() {}     } ... Any suggestion on this? Stability thing, mainly from dns proxy.  After running for a while with both proxies, name resolution failed. We will go on checking this point as well.
