hi all,
I am relatively new to openWrt but I have been playing around with it for a while. I am however new to this forum, so I apologize if I am in the wrong thread.
I am using it on a TPLink router to provide access to a nordvpn connection on my smart tv.
The problem is that there are some smartTV applications for which I need one VPN, some for which I need another, and others for which I need a non-vpn connection. I therefore tried domain-based routing using VPN-Policy-Routing. But the number of domains accessed by each application is large (CDNs) and I do not exclude that multiple applications that I need to use different VPNs are using the same akamai-based domain.
So I thought of the following solution.
Since the SmartTV uses one application at a time, I would like to react to the first dns request, which I can easily track, and switch to the right VPN connection.
Is there an API that allows me to react to DNS queries? Or do I need to use the logging feature?
In particular, I was thinking I could use the logging feature of dnsmasq, and build a small local log server that receives log entries, reacts to requests for the right domains and switches routes. This would work, but I wonder if there would be a better solution.
thanks
bye
Dave
