It would be cool if there was a feature where when FTL was doing gravity, adding or removing items from whitelist, blacklist, regex, etc. to have it make IP tables rules to forward DNS requests to the upstream servers until all tasks are done. Now I know I can setup primary and secondary DNS in my router, but it would be nice if we could at least get some resolution while it is doing intensive tasks. I don’t know if the new api and version 5.0 could be built to handle something like this.
I have about 4 million domains being blocked, 50 regex rules, 20 items in the whitelist and few items on the blacklist. The web interface and DNS freezes when I have to update any of these for whatever reason.
