[quote='841312022, DTS Engineer, /thread/786122?answerId=841312022#841312022'] Is that right? That’s 8 possible combinations. Which ones work and which ones fail? [/quote] That's right, the solution uses (at least tries to) those three components, although we can omit Content Filter in the context of this problem, because I've already confirmed that its presence doesn't make a difference. The problem I'm facing is with the use of Packet Tunnel Provider and DNS Proxy Provider, because separately they do work (including in a pair with Content Filter), but after turning Packet Tunnel on with a running DNS Proxy, the internet connection fully drops – no new flows in the DNS Proxy and no packets going through the tunnel. All of the further context is provided in the original post.

In addition, if I uncomment the dns settings in my tunnel settings setup, and use PacketTunnel and DNSProxy like this, the internet does work, but as I understand it that's thanks to the tunnel taking over the dns handling, therefore the proxy doesn't receive anything. Based on this behavior I'm not that sure if it's really possible to use both the tunnel and dns proxy in the way I want to.
