Hello, Regarding this explanation If this property is YES, the system excludes network connections to hosts on the local network — such as AirPlay, AirDrop, and CarPlay — but only when the includeAllNetworks or enforceRoutes property is also YES. So my question is the local network here only meaning AirPlay, AirDrop, and CarPlay? Is the pings to local LAN IP still working? What is the exactly the local network definition here? Is it based on the interface or the IPs? For example, somehow we connects to a wifi which assigned a public IP. After VPN is connected with tunnel all mode, we set includeAllNetworks and excludeLocalNetworks flag, will the traffic originally goes through wlan interface goes through utun interface? Or it will keep going through wlan interface?

[/quote] Apple platform do have something like this — like I said, two of everything! (-: — namely NECP. For some very limited details on that, see A Peek Behind the NECP Curtain. However, as a third-party developer you have a very limited view into NECP, and it certainly won’t help with this. The go-to doc on this is Routing your VPN network traffic. It explains: How includeAllNetworks represents a giant switch, which effectively disables destination IP routing. This setting is implemented using NECP. How enforceRoutes lets you continue using destination IP routing but prevents apps from bypassing that.

The .includeAllNetworks flag on the NEVPNProtocol object seems suitable for use as a vpn kill switch. At the very least, the documentation specifies that if this value is true and the tunnel is unavailable, the system drops all network traffic. Our application has a UI element that allows the user to toggle this setting, for the purposes of ensuring that all of their traffic is sent through the VPN connection. We're encountering an issue, however: it appears that, with this setting enabled, any NWTCPConnection returned by NEPacketTunnelProvider.createTCPConnectionThroughTunnel will never connect. It stays in the .connecting state and never advances to the .connected state. The documentation for this method states that this method can be used to create a TCP connection to an endpoint inside the private network. Does this mean that the remote endpoint being connected to by createTCPConnectionThroughTunnel must reside inside the private network being connected to by the tunnel in order for it to work pr
Hi Matt,I able to fix the IPC issues. Now i could see it is saving the configuation correctly. But next my expectation was to get the callback on App proxy provider(i.e. AppProxyProvider) but not getting the callback. Looks like it is not able to get into the network system extension. Network preference, extension status showing as Connecting...) Any thought please?

Recently I tested my VPN application on iOS 15 beta 8 / Xcode 13 beta 5. It looks like that the precedence is IPSec VPN > iCloud private relay > NEPacketTunnelProvider VPN. When the iCloud private relay is switched on if use IPSec VPN(I think it's using the IPSec interface) the browser's network traffic is still being routed to the IPSec tunnel. But for the implementation with NEPacetTunnelProvider VPN(UTUN interface) the browser's traffic is being routed to the private relay. I don't see any doc describing this but it seems this is the design. And another question is the IncludeAllNetworks setting for the VPN. If set the IncludeAllNetworks to be 1 then the device global traffic would be routed to the VPN, but the excludedRoutes settings in the VPN would be unavailable, no routes would be excluded. Is the above understanding correct?
When trying to bind a socket to the tunnel interface via setsockopt(socket, IPPROTO_IP, IP_BOUND_IF, &ifindex, len) Within the PacketTunnel itself despite this call succeeding the data is still routed through the default interface. This is observed when includeAllNetworks is true. When it is false it seems to send it on both interfaces. Is there something wrong with how I'm doing it?
Hi, I'm new in this area. I have several questions to ask. I'm implementing a vpn client by using NETunnelProviderProtocol(). After I start the tunnel successfully, I can't get any packets from self.packetFlow.readPacketObjects. Is the NETunnelProviderProtocol able to gather the packet from whole device ?(just work like a normal vpn client) Is it safe to turn includeAllNetworks() to true? thanks
In our PacketTunnelProvider we are seeing behavior for enforceRoutes which appears to contradict the documentation. According to the developer documentation (my emphasis): If this property is YES when the includeAllNetworks property is NO, the system scopes the included routes to the VPN and the excluded routes to the current primary network interface. If we set these IPv4 settings: IPv4Settings = { configMethod = manual addresses = ( 172.16.1.1, ) subnetMasks = ( 255.255.255.255, ) includedRoutes = ( { destinationAddress = 0.0.0.0 destinationSubnetMask = 0.0.0.0 }, ) excludedRoutes = ( { destinationAddress = 10.10.0.0 destinationSubnetMask = 255.255.255.0 }, ) overridePrimary = YES } Then if enforceRoutes is set to YES, then we do not see traffic for the excluded network, which is the expected behavior. If enforceRoutes is set to NO, then we do see traffic for the excluded network. In both cases includeAllNetworks and excludeLocalNetworks are both NO. The excluded network is not one of the
Requirement: We need to update below tunnel provider properties once VPN is up. Is it possible? includeAllNetworks excludeLocalNetworks enforceRoutes When is the standard time to configure and save the below properties in system preferences? Is it possible to save these properties in system preference when VPN is up? saveToPreferencesWithCompletionHandler If we can change these properties in VPN connected state, When these tunnel provider properties will come into effect?
Hello, im currently developing proxy app with XrayCore trying to bypass APNs when tunnel us up and i found .excludeAPNs property in NETunnelProviderProtocol that works only when includeAllNetworks property is also TRUE. I wonder if there is a possible way to make APNs bypass tunnel in split tunnelling mode? because we use excludedRoutes and full tunnel is not an option
I am connecting to VPN connection with NEPacketTunnelProvider configuration as IncludeAllNetworks=YES; ExcludeLocalNetwork=NO; which is tunneling all the traffic generated on my device which is expected. But Once I disconnect and kill the NEPacketTunnelProvider instance, My internet is blocked unless I restart the device. This behavior is not seen with iOS 16 and things work smooth. Kindly update as soon as possible
I've implemented a custom system extension VPN for macOS using a Packet Tunnel Provider. At the Protocol Configuration, the 'includeAllNetworks' flag is unset. At the provider, I included all routes (IPv4 default route). What is the expected behavior for LAN traffic? Should the LAN traffic go via the VPN? By 'LAN traffic', I'm referring to local hosts, ssh, printer access, etc.
Hey! We discovered an unexpected side-effect of enabling enforceRoutes in our iOS VPN application - video airplay from iOS to tvOS stopped working (Unable to Connect popup appears instead). Our flags combination is: includeAllNetworks = false enforceRoutes = true excludeLocalNetworks = true Interestingly, music content can be AirPlayed with the same conditions. Also, video AirPlay from iOS device to the macOS works flawlessly. Do you know if this is a known issue? Do you have any advice if we can fix this problem on our side, while keeping enforcRoutes flag enabled?
Now that the flag includeAllNetworks is working as expected (see https://developer.apple.com/forums/thread/722156), I tried to set it and also the ExcludeLocalNetworks flag. As described in the documentation, I'm able to use AirPlay and AirDrop while being connected, but what I was hoping for was to exclude from the tunnel all the LAN traffic, including pings to local hosts, ssh, printer access, etc. Isn't it what ExcludeLocalNetworks should accomplish? If not, how can I exclude LAN traffic from a full tunnel (i.e. not a split tunnel)? [Custom VPN, macOS, Packet Tunnel Provider, system extension]
Hi, I'm new to iOS development and would like to gain some understanding about how NEPacketTunnelProvider handles for UDP traffic. In my code, I've created NEPacketTunnelNetworkSettings let settings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: proxyHost) let ipv4Settings = NEIPv4Settings( addresses: [127.0.0.1], subnetMasks: [255.255.255.255] ) settings.ipv4Settings = ipv4Settings let proxySettings = NEProxySettings() ... settings.proxySettings = proxySettings and passed it to the setTunnelNetworkSettings function. And I was able to start the VPN with no issues. However, in the debug tool, I couldn't see any UDP traffic which I'm sure there should be some. The only UDP connection had no traffic constantly. Does the NEProxySettings only work for TCP? What am I missing here? (I've set protocolConfiguration?.includeAllNetworks = true in my NETunnelProviderManager) Thanks
