Reply to includeAllNetwork Problems.
includeAllNetworks covers a lot more than setting the default route. We need the extra assurance that all traffic will be handled, and that the tunnel won't leak. Defining it at config definition time is a pain, but I can work around that. The main issue I see at this point is that when I define includeAllNetworks and it takes effect, I can no longer connect to the gateway, even by IP address.

Hello Kevin, It looks like includeAllNetworks has to be set on the VPN configuration when it's defined. Is that correct? Yes. Is there any way to set this on-the-fly? In our particular VPN interaction the Gateway tells the VPN client whether it wants the client to use includeAllNetworks, so we can't just hard-code it. Since includeAllNetworks forces all traffic through the virtual interface, if you need to make a configuration network call that needs to go outside the tunnel then this needs to be done while the tunnel is not configured or active. default 13:42:57.476293-0700 VPNExtension [C10 Hostname#0a01000a:443 failed path (unsatisfied (Path was denied by NECP policy), interface: en0, ipv4)] event: null:null @4.222s Right, if possible, I would gather the network configuration information before the tunnel is started, otherwise using this flag will not work for this case.

Is there any other place in the system where VPN configs can be found? For macOS, System Preferences - Network is the standard place. You can use % scutil also to take a look at the Network Configurations via % scutil --nc list. If you do not include IncludeAllNetworks are you able to connect your tunnel?

Failed to register Personal IncludeAllNetworks VPN Session NESMIKEv2VPNSession
As described in a few threads here, it is not possible to set IncludeAllNetworks to true on NEVPNProtocolIKEv2 if there are any Enterprise VPNs with NEVPNProtocolIKEv2 enabled, even if they are not used at that moment. The problem I faced, is that system does not have any other VPN configs listed in System Preferences - Network, but connection still can't be established with error: Failed to register Personal IncludeAllNetworks VPN Session NESMIKEv2VPNSession due to Enterprise VPN session NESMVPNSession. Is there any other place in the system where VPN configs can be found?

Hi, from what I understand it appears this is not possible to set on-the-fly and it can be configured only when installing the profile.. In my testing this includeAllNetworks behaves quite similarly to settings includedRoutes on the IPV4Settings to NEIPv4Route.default(). This could possibly be set when starting the tunnel, so you would need to stop and start again to toggle this.

includeAllNetwork Problems.
I've been looking at adding includeAllNetworks to our Network Extension VPN (Packet Tunnel Provider). We do some authentication in the app and then start the VPN. All connections in the VPN extension are done by IP address, so there is no name resolution required. The connection setup in the VPN extension involves some HTTP GETS & responses. I'm seeing a couple of problems. It looks like includeAllNetworks has to be set on the VPN configuration when it's defined. Is that correct? When I try setting it at other points, either in the NEPacketTunnelProvider protocolConfiguration or in the NEVPNManager protocol configuration it has no effect. The protocol itself appears to be inaccessible. When I set it in the NEVPNManager's protocolConfiguration before I start the connection it shows includeAllNetworks as set, but when I start the connection the nesessionmanager debug output shows that it's not set in the protocol and it's not in effect. Is there any way to set this on-the-fly?

Reply to NEPacketTunnelProvider does not seem to be capturing all the traffic
Apologies for talking to myself there 🤪 but I made interesting discovery. If I use the includeAllNetworks configuration - https://developer.apple.com/documentation/networkextension/nevpnprotocol/3131931-includeallnetworks, then this finally seems to rein in Messenger and does not let is around the tunnel. That is great but it has the side-effect of once again breaking Signal, WhatsApp and probably other similar apps. I checked Signal debug logs and found that I cannot find a server by hostname. Which suggested DNS issue. So I re-added DNS configuration, added these IPs to the excludedRoutes and now Signal works but only one way. I can send messages, they are delivered but I cannot receive messages. I still think that the fact that Messenger can just go around the tunnel is the main issue.

Reply to Traffic originated at the PacketTunnelProvider [lib-curl]
I'm using lib-curl from the provider. The traffic is not going via the tunnel. Is it possible to pass this traffic to the tunnel? I just want to confirm; are you including libcurl interfaces or a custom version of libcurl in your Packet Tunnel Provider, sending traffic via these APIs, and not seeing this traffic pass through the tunnel? If this is the case, you could look into using an In-Provider networking class like NWTCPConnection. - https://developer.apple.com/documentation/networkextension/nwtcpconnection If you are using libcurl for the HTTP stack you could also take a look at the CFMessage APIs, depending on how complicated your requests are. What should happen if I'll set the 'capture all traffic' flag? Will the traffic created from lib-curl at the provider will reach the tunnel? If you mean setting the flag for includeAllNetworks on NEVPNProtocol then, yes, all traffic should go through the provider in this instance. Matt Eaton DTS Engineering, CoreOS meaton3@apple.com

Reply to Failed to register Personal IncludeAllNetworks VPN Session NESMIKEv2VPNSession
Matt, you mean even if none of the profiles are active (connected)? If I delete all of the vpn profiles in Network preferences, only then I can connect NEVPNProtocolIKEv2 profile with IncludeAllNetworks flag. As soon as I add any other vpn profile I am no longer able to connect my IKEv2 profile. The rules I had previously researched and posted about were logical rules that exist on the system under the hood. It sounds like your test is confirming that it is you can have a conflicting VPN profile if you have another VPN profile (Personal or Enterprise) that is installed on the system, but not active, and also contains the includeAllNetworks flag. Is that correct? If so, you should file an enhancement request - https://developer.apple.com/bug-reporting/ to document this behavior. Matt Eaton DTS Engineering, CoreOS meaton3@apple.com

Reply to Failed to register Personal IncludeAllNetworks VPN Session NESMIKEv2VPNSession
Ok, there's definitely a strange behaviour. If I delete all of the vpn profiles in Network preferences, only then I can connect NEVPNProtocolIKEv2 profile with IncludeAllNetworks flag. As soon as I add any other vpn profile I am no longer able to connect my IKEv2 profile. Even if I manually add some IPSec profile via Network prefeneces 🤯. This makes IncludeAllNetworks flag impossible to use in my vpn app.

default 19:05:54.375325+0200 nesessionmanager nesessionmanager : Failed to register Personal IncludeAllNetworks VPN Session Okay, the line above does mean that a Personal and Enterprise VPN on your system cannot both have the flag for IncludeAllNetworks. The Enterprise VPN will take precedence here and the Personal VPN will be stopped with this message that you are seeing. Matt Eaton DTS Engineering, CoreOS meaton3@apple.com

Reply to With VPN switched on no messages can be seen on console and can not connect with Xcode
First, thank you for opening the bug report. I see it internally and have copied myself on it. A few things to note here; You mentioned: A VPN application coded with NETunnelProvider, set 'includeAllNetworks' to be true (if it's false then cannot reproduce this issue); Install the VPN application on the iPhone and switch it on; Connect the iPhone to the Mac Book Pro with a USB cable; If you test with either includeAllNetworks to be false or plugging in the iPhone device before you start the tunnel does it workaround this issue?
