Though I use #LittleSnitch I turned on #macOS's firewall on 2022/11/02 - figuring why not?. A few days *before* Ventura 13.2 on 2023/01/24 and several *days after* a reported update to XProtect Remediator I started having issues with my wireless and wired network connections - the "dreaded No Internet Connection / Self-assigned IP address". After days of trials I finally had the bright idea of turning the macOS firewall back off. TaDa, no more issues. Grr, mysteries without an immediate cause.
