Is it possible to direct inbound sinkhole traffic to a custom IP on ports 80/443?
I am trying to see if I am able to redirect traffic hitting our "geolocation block" rule and redirect it to a block page.
@NevinNIt's not possible, with DNS sinkhole Palo Alto device forge a response to DNS query for suspicious domain/URL and causes that domain/URL to resolve defined IP address. So here no possibility of your use case as it is just happening while querying DNS.
You can do one thing, if you have proxy/PAC file script in your environment, you can defined some page for sinkhole IP. So if anyone tried any suspicious domain/url from browser then palo alto will resolve its dns query to sinkhole IP and proxy/PAC file script will give appropriate page for that traffic.
Hope it helps you!
