[QUOTE="davegson, post: 1012991, member: 92101"] Hey there, the incompatibility is created when both Portmaster and a VPN client hook into DNS. Check your VPN app if you can somewhere disable DNS redirection. Portmaster [I]needs[/I] to hook into DNS in order to understand which connection goes where and to which app it belongs. Without it, users would have to start filtering by IP address, making PM basically useless. Portmaster automatically secures DNS requests by encrypting them to a secured DNS resolver - which you can configure if you do not like the defaults. You can even set your VPN provider as the resolver if you want. We are all about empowering users. VPNs, as yours, do sometimes hook into DNS too - creating the compatibility conflict. Their idea is that since you redirect all your normal traffic through them, you might as well redirect all your DNS to them too. Now that comes from good intentions - but if they do not provide a way to disable this behavior, then this goes against user choice. There sadly is not much we can do than to ask VPN providers to empower users and allow them to disable their DNS integration. An alternative for technical users like the folks at MalwareTips is to set up Portmaster with the OpenVPN workaround: [URL unfurl="true"]https://docs.safing.io/portmaster/install/status/vpn-compatibility#workaround-openvpn[/URL] Hope this explains the situation.
