I would need to virtualy split a single dnsdist instance in the the way, that clients sendig request to a particular IP od DNS dnsdist (listening on multiple IPs) are sent to a dedicated pool. I could start another dnsdist process bound to the secondary IP on the server but I think there must be a more lelegant wa to do it ;-) It should work this way:client1 ---> DNS req. to dnsdist IP1 ---> pool-A ---> cache-A ---> backend A client2 ---> DNS req. to dnsdist IP2 ---> pool-B ---> cache-B ---> backend BIs there a way to match a destination IP of the client's request in a rule in order to send it to a pool? I can not use client's IP here.
Unless I'm mistaken you should be able to do that with NetmaskGroupRule [1], setting the "src" parameter to false to match the destination instead of the source.
