Hello, any good ideas for implementing the split tunnel for NEPacketTunnelProvider? I don't want all the traffic going through the VPN

How to reconfigure NEPacketTunnelNetworkSettings on network changes?

Hi!

First of all, thank you, your code is super helpful.

I need to change the
tunSettings.dnsSettings = NEDNSSettings(servers: [])
based on the user current IP address (wifi or cellular ) -- I'm listen to network events with Reachability library and together with on-demand rules I thought I can simply do

reachability.whenReachable = { reachability in if reachability.connection == .wifi { self.stopTunnel(with: .none, completionHandler: {print("asdasd")}) } else { self.stopTunnel(with: .none, completionHandler: {print("asdasd")}) } }

but it doesn't stop the tunnel, when I debug it, I can see that it's been called , but the tunnel stays connected..

when I manually turn the connection off, the on-demand rules kick off and my startTunnel function called.

To summarize, I want to be able to reconfigure NEPacketTunnelNetworkSettings object every time the user changes his public ip.

Thank you very much!

Doesn't work startVPNTunnel

Hi,

Thank you for your repo and your blog. It is useful for me to study iOS and VPN system.

After reading your blog(https://kean.blog/post/vpn-configuration-manager), I tried to compile this repo on my Xcode.
But It didn't work correctly.
I debugged these codes and found out the point where it didn't work.

buttonStartTapped()
try tunnel.connection.startVPNTunnel

Of couse, I fixed Bundle identifier, and change com.github.kean.* to my app's settings. But it doesn't work...
Any help?
